English, Scientific journal, This study presents a trial analysis that uses brain activity information obtained from mice to detect rheumatoid arthritis (RA) in its presymptomatic stages. Specifically, we confirmed that F759 mice, serving as a mouse model of RA that is dependent on the inflammatory cytokine IL-6, and healthy wild-type mice can be classified on the basis of brain activity information. We clarified which brain regions are useful for the presymptomatic detection of RA. We introduced a matrix completion-based approach to handle missing brain activity information to perform the aforementioned analysis. In addition, we implemented a canonical correlation-based method capable of analyzing the relationship between various types of brain activity information. This method allowed us to accurately classify F759 and wild-type mice, thereby identifying essential features, including crucial brain regions, for the presymptomatic detection of RA. Our experiment obtained brain activity information from 15 F759 and 10 wild-type mice and analyzed the acquired data. By employing four types of classifiers, our experimental results show that the thalamus and periaqueductal gray are effective for the classification task. Furthermore, we confirmed that classification performance was maximized when seven brain regions were used, excluding the electromyogram and nucleus accumbens. - Expert–Novice Level Classification Using Graph Convolutional Network Introducing Confidence-Aware Node-Level Attention Mechanism

Japanese, Measuring the CO2 absorption of algal beds is one of the key issues for achieving carbon neutrality, but identifying the area of algal beds from UAV images requires a great deal of labor and experience. In this study, we propose a method for automatic recognition of algal beds using UAV images. The proposed method uses a model that enables semantic domain segmentation at the pixel level, and employs ViT-Adapter, one of the latest models. The advantage of this technique is that it effectively utilizes the knowledge of a trained large-scale model to recognize algal beds, and it can identify algal beds at the pixel level by adjusting the parameters of the model. In this study, we conducted learning using mask images of visually identified algal beds from aerial photographs, and further examined data expansion and other processing to adapt the learning to UAV images. The effectiveness of this method was verified through a demonstration using UAV images of the Erimo coast of Hokkaido. - Generative Dataset Distillation: Balancing Global Structure and Local Details.

Japanese, Skill transfer to young engineers from senior engineers is a very important task in infrastructure equipment inspection. To support the skill transfer, an analysis method of the key factors of senior engineers skill is needed. However, conventional research has been limited to skill-level classification or analysis of the relationship between the skill level and biological data such as eye gaze and motion obtained from the engineers. This paper presents a method of classifying the skill level and visualization of its key factors to support the skill transfer. The proposed method employs a graph convolutional network introducing a novel attention mechanism for the classification and visualization. - Accident risk estimation with depth information in construction site videos

Japanese, In the construction industry, reducing accident risk and improving safety is one of the high-priority tasks. Recently, several methods have been proposed to estimate the contact accident risk with heavy machinery on construction sites for enhancing safety. Conventional studies based on deep learning estimate the risk by using relations within the image space of detected workers and machinery captured in construction site videos. However, these approaches focus on the distance between detected objects in the image, leading to the problem that accident risk is overestimated even when there is distance between objects in the real world. In this study, to consider 3D spatial information in videos, we propose a method for estimating the accident risk with visual features regarding depth information. Experimental results show that the proposed method performs better than existing methods in estimating the contact accident risk. - Reinforcing Pre-trained Models Using Counterfactual Images.

English, Scientific journal, Abstract
Aims
Although frailty assessment is recommended for guiding treatment strategies and outcome prediction in elderly patients with heart failure (HF), most frailty scales are subjective and the scores vary among raters. We sought to develop a machine learning-based automatic rating method/system/model of the clinical frailty scale (CFS) for patients with HF.
Methods and Results
We prospectively examined 417 elderly (≥75 years) with symptomatic chronic HF patients from seven centers between January 2019 and October 2023. The patients were divided into derivation (n = 194) and validation (n = 223) cohorts. We obtained body-tracking motion data using a deep learning-based pose estimation library, on a smartphone camera. Predicted CFS was calculated from 128 key features, including gait parameters, using the Light Gradient Boosting Machine (LightGBM) model. To evaluate the performance of this model, we calculated Cohen’s weighted kappa (CWK) and intraclass correlation coefficient (ICC) between the predicted and actual CFSs. In the derivation and validation datasets, the LightGBM models showed excellent agreements between the actual and predicted CFSs (CWK 0.866, 95% CI 0.807-0.911; ICC 0.866, 95% CI 0.827-0.898; CWK 0.812, 95% CI 0.752-0.868; ICC 0.813, 95% CI 0.761-0.854, respectively). During a median follow-up period of 391 (IQR 273-617) days, the higher predicted CFS was independently associated with a higher risk of all-cause death (HR 1.60, 95% CI 1.02-2.50) after adjusting for significant prognostic covariates.
Conclusion
Machine learning-based algorithms of automatically CFS rating are feasible, and the predicted CFS is associated with the risk of all-cause death in elderly patients with HF. - Zero-Shot Traffic Sign Recognition Based on Midlevel Feature Matching

Scientific journal, Traffic sign recognition is a complex and challenging yet popular problem that can assist drivers on the road and reduce traffic accidents. Most existing methods for traffic sign recognition use convolutional neural networks (CNNs) and can achieve high recognition accuracy. However, these methods first require a large number of carefully crafted traffic sign datasets for the training process. Moreover, since traffic signs differ in each country and there is a variety of traffic signs, these methods need to be fine-tuned when recognizing new traffic sign categories. To address these issues, we propose a traffic sign matching method for zero-shot recognition. Our proposed method can perform traffic sign recognition without training data by directly matching the similarity of target and template traffic sign images. Our method uses the midlevel features of CNNs to obtain robust feature representations of traffic signs without additional training or fine-tuning. We discovered that midlevel features improve the accuracy of zero-shot traffic sign recognition. The proposed method achieves promising recognition results on the German Traffic Sign Recognition Benchmark open dataset and a real-world dataset taken from Sapporo City, Japan. - Machine Learning-Based Prediction of Clinical Frailty Scale Based on Gait Analysis in Elderly Patients With Heart Failure

Japanese, Supervised multi-view canonical correlation analysis via cyclic label dequantization (sMVCCA-CLD) for visual emotion recognition is presented in this paper. In the CCA approach, the dimension of latent common space is limited to the minimum dimension among those of all features. The dimension of label features i.e., the number of classes for label information, tends to be lower than those of the other features. Then the dimension of the latent common space constructed by CCA becomes lower. Therefore, there is a possibility of misssing important information that is necessary for the estimation from the latent common space due to the dimensionality constraint. To overcome this constraint, sMVCCA-CLD increases the dimension of the label features by the label dequantization process, and estimates the canonical correlation between multi-view features. In addition, sMVCCA-CLD performs the label dequantization considering that the emotions are represented by a cyclic model, e.g., Plutchik's and Mikel's wheels.

Japanese, In this study, we propose a novel method for automatic generation of findings using a visual language model to support the efficient creation of findings in inspection records for infrastructure facilities. It is essential for the creation of inspection records to write findings, which are sentences that include judgments and opinions of engineers in addition to what can be recognized from the distress image. However, there has been little discussion on the direct automatic generation of findings, and it is expected to realize generation methods to support the efficient creation of findings. With this background, in this paper, we introduce few-shot learning based on the similarity of distress images to the visual language model, which is an application of large language models attracted much attention in recent years and enables text output with a highly accurate understanding of both vision and language. By using past inspection records including images similar to the distress images, we can efficiently consider the relationship between the distress images and findings from a small number of pairs of them. In the last part of this paper, we confirm the effectiveness of the proposed method through experiments generating findings from the distress images included in the inspection records of bridges. - Distress estimation of road attachments based on attention-based multiple instance learning considering the diversity of background of images

Japanese, In this paper, we propose a distress estimation method for road attachments. Road attachments, such as signs and lighting, are equipped over a huge number and wide area, and therefore it is desired to achieve automatic inspection by using drones to reduce the burden on the inspectors. While captured images by drones include the diversity of the background including ground, sky, and road surfaces, the previous methods did not consider the diversity of the background of captured images of road attachments. This study proposes the distress estimation method via attention-based multiple instance learning to address this issue. We input patches of the images into the estimation model to distinguish between the background area and road attachment area and assign importance weight, or attention, to each patch. By performing this strategy, we realize the distress estimation method considering the diversity of the background area of images. In the experiment, we achieve a classification accuracy of about 70 % using images of actual road attachments confirming the effectiveness of this research approach. - Multi-task classification of distress types and deterioration levels for infrastructure maintenance

Artificial Intelligence and Data Science, 4, 3, 807, 814, Japan Society of Civil Engineers, 2023
Japanese, This paper proposes a multi-task classification method that classifies both the distress type and deterioration level at the same time. Conventionally, classifying the deterioration level has been conducted for each distress type by using multiple models. In contrast, the proposed method enables classification of the deterioration level without assigning a distress type to the distress image in advance, by training a single model through loss minimization considering the distress type and deterioration level. In the last part of the paper, it is verified that the proposed method can achieve classification performance equivalent to models constructed for each distress type with a single model by using images of actual distress that have occurred on infrastructure. - Advanced AI research for enhancing the efficiency of infrastructure maintenance and management

Artificial Intelligence and Data Science, 4, 3, 982, 989, Japan Society of Civil Engineers, 2023
Japanese, With the development and advancement of AI technology, research on the application to the field of infrastructure maintenance is actively progressing. Many of these studies focus on the development of learning theories that consider the characteristics of images obtained in infrastructure maintenance. The effectiveness of AI has been demonstrated in various tasks such as crack detection, classification of defect types, and estimation of degradation levels. On the other hand, to truly enhance the operational efficiency through AI, it is necessary to construct AI systems considering the practical business. Furthermore, to improve AI and continuously utilize AI, it is necessary to acquire images suitable for AI development in operations. Therefore, this paper introduces the learning theories that have been developed for images obtained in infrastructure maintenance, previous research on AI with essential function for the practical business and the authors’ idea on efficient image acquisition. - Automatic detection of dead trees using in-vehicle video based on semantic segmentation

Scientific journal, Abstract
This review aims to clarify a suitable method towards achieving next-generation sustainability. As represented by the term ‘Anthropocene’, the Earth, including humans, is entering a critical era; therefore, science has a great responsibility to solve it. Biomimetics, the emulation of the models, systems and elements of nature, especially biological science, is a powerful tool to approach sustainability problems. Microscopy has made great progress with the technology of observing biological and artificial materials and its techniques have been continuously improved, most recently through the NanoSuit® method. As one of the most important tools across many facets of research and development, microscopy has produced a large amount of accumulated digital data. However, it is difficult to extract useful data for making things as biomimetic ideas despite a large amount of biological data. Here, we would like to find a way to organically connect the indispensable microscopic data with the new biomimetics to solve complex human problems. - DETERIORATION LEVEL CLASSIFICATION OF DISTRESS IMAGE CONSIDERING CORRELATION AMONG HETEROGENEOUS FEATURES AND ATTENTION MAP CONFIDENCE

English, This paper presents human-centered video feature selection via mRMR-SCMMCCA (minimum Redundancy and Maximum Relevance-Specific Correlation Maximization Multiset Canonical Correlation Analysis) algorithm for preference extraction. The proposed method derives SCMMCCA, which simultaneously maximizes two kinds of correlations, correlation between video features and users' viewing behavior features and correlation between video features and their corresponding rating scores. By monitoring the derived correlations, the selection of the optimal video features that represent users' individual preference becomes feasible. - Extracting Hierarchical Structure of Web Video Groups Based on Sentiment-Aware Signed Network Analysis

Japanese, In this paper, we propose a category classification method of tourism images in image sharing services. First, the proposed method performs classification of tourism images by applying a fuzzy K-nearest neighbor algorithm to the location feature vectors and newly estimates their confidence measures. Second, if the confidence measures of the classification results are lower, the proposed method performs decision level fusion of related visual and textual tag feature vectors to obtain final classification results. Consequently, the proposed method enables successful integration of multiple classification results obtained from the several kinds of features based on the above two stage classification scheme. - NMF-Based Spectral Reflectance Estimation From Image Pairs Including Near-Infrared Components

English, This paper presents automatic Martian dust storm detection from multiple wavelength data based on decision level fusion. In our proposed method, visual features are first extracted from multiple wavelength data, and optimal features are selected for Martian dust storm detection based on the minimal-Redundancy-Maximal-Relevance algorithm. Second, the selected visual features are used to train the Support Vector Machine classifiers that are constructed on each data. Furthermore, as a main contribution of this paper, the proposed method integrates the multiple detection results obtained from heterogeneous data based on decision level fusion, while considering each classifiers detection performance to obtain accurate final detection results. Consequently, the proposed method realizes successful Martian dust storm detection. - Image Classification Based on Integration of EEG and Visual Features Via LFDA-MSLPCCA

English, In this paper, we present an adaptive spatial-temporal error concealment method for the wavelet based video coding in wireless networks. A three-dimensional discrete wavelet transform (3-D DWT) is performed 2-D spatial DWT coding and temporal DWT coding on a group of pictures (GOP). The transmission of compressed video suffers from errors such as packet losses that not only corrupt frame but also propagate successive frames. The proposed adaptive spatial-temporal error concealment method consists of spatial EC and temporal EC to overcome error propagation problems. The proposed method is concealing erroneous coefficients of the spatiotemporal low-frequency subband by their duplication information, and uses the proposed adaptive spatial-temporal concealment method to recover errors for entire video sequence. The performance of proposed method was evaluated with wireless packet transmission networks. Experimental results show the proposed method can serve robust and stable performance in error-prone environments. - Error-Resilient 3-D Wavelet Video Coding with Duplicated Lowest Sub-Band Coefficients and Two-Step Error Concealment Method

日本メディカルセンター - A Proposal and Evaluation of a New Method Incorporating Indicators of Blood Flow and Resistance to Improve the Accuracy of Continuous Blood Pressure Estimation Using PPG

This paper presents a new method which achieves accuracy like cuff-based BP (Blood pressure) measurement to improve the conventional cuff-less BP estimation method for a wrist-type single PPG sensor. The conventional method used the modified normalized pulse volume and the pulse rate for resistance and flow rate respectively to express BP. However, it is required to improve the performance in comparison with methods based on pulse wave velocity which involve elasticity rate relating to vascular pressure. The new method incorporates both resistance which is derived from relative velocity and peripheral arterial elasticity based on vascular function to elevate the accuracy of diastolic BP estimation. Systolic BP is also improved by the sum of estimated pulse pressure with resistance and the estimated diastolic BP value. The accuracy comparison between the conventional and proposal method was performed by cross validation for estimated BP values in 5 seconds each by using wrist-type PPG signals. It is found that the estimated SBP and DBP of the conventional method differed from the reference BP by 3.9 (mean absolute error) ±12 (standard deviation) mmHg and 4.7 ± 11 mmHg respectively. In the proposal method, the differences of estimated values are 2.5 ± 7.2 mmHg and 2.7 ± 7.8 mmHg. When compared to the AAMI requirement (5 ± 8 mmHg for both SBP and DBP estimation), the results suggest that the proposed method has great potential for a single PPG sensor device., The Institute of Electrical Engineers of Japan, Japanese - A Note on Estimation of Semantic Content Based on a Question Answering Model Using Brain Activity Data while Viewing Images-Improvement of Estimation Performance Based on fine-tuning of the VQA model-

原発性シェーグレン症候群(Sj?gren's syndrome, SS)は慢性唾液腺炎と乾燥性角膜炎を主徴とする自己免疫疾患である.小児膠原病疫学調査において若年性特発性関節炎,全身性エリテマトーデスに次ぐ高頻度な疾患であることが明らかにされた.小児では目や口の乾燥を呈する腺症状ではなく,非特異的な症状で受診する例が多い.今回,日常生活に支障をきたすほどの全身倦怠感や発熱の反復などの症状を認めながら,長期間にわたり起立性調節障害(Orthostatic Dysregulation, OD)と診断されていたSSの1例を経験したので報告する.症例は14歳女児.12歳時にめまいと一時的な両下肢の筋力低下を自覚したのを契機にODと診断された.その後も頻回な倦怠感を訴え,複数の診療科・施設でODと診断されていた.14歳時に発熱,嘔吐,腹痛,下腿紫斑を主訴に前医に入院し,アレルギー性紫斑病の疑いでプレドニゾロン(PSL)の投与を開始された.しかし,症状改善せず,多様な所見が加わったため当科に紹介となった.抗核抗体,抗SS-A/Ro抗体,抗SS-B/La抗体が陽性,ガム試験と口唇小唾液腺生検がSSの診断基準を満たし,原発性SSと診断した.PSLは漸減中止しNSAIDsの内服を開始したが,低血圧および全身倦怠感が増悪した.その後,昇圧剤やPSLの内服を再開するも症状のコントロールが困難だったため,免疫抑制剤を投与した.現在はPSL,シクロスポリン,昇圧剤の内服を併用し加療中である.倦怠感や原因不明の発熱や皮疹などの症状を繰り返す症例では,腺症状がなくともSSの可能性を考慮し,精査する必要性があると考えられた., 昭和大学学士会, Japanese - A note on accurate retrieval of similar inspection records based on canonical correlation between eye tracking data and inspection records

The Institute of Image Information and Television Engineers, Japanese - Selection of Summer-to-autumn-flowering Small-flowered Spray-type Chrysanthemums for Fine Control of Flowering Using Light Culture
Mori Yoshio, Nagai Towa, Yano Shinobu, Ogawa Takahiro, Hirose Nobuo, Oda Atsushi, Nakano Yoshihiro, Hisamatsu Tamotsu, Sumitomo Katsuhiko, Suzuki Yasukazu, Yamagata Atsuko, Murazaki Satoshi, Takada Mami, Yabuki Takao, Yokoi Naoto, Mato Masami, Tazuke Hiroshi, Horticultural Research (Japan), 16, 1, 27, 39, 2017We developed a method to select summer-to-autumn-flowering small-flowered chrysanthemum cultivars suitable for the fine control of flowering using light culture. Budding under non-inductive night-break conditions was investigated from March to May. 'Subaru' and 'Sei-chigusa' showed no budding under night-break conditions during experimental periods. However, 'Sei-shimanami' showed a seasonal change in budding under night-break conditions, being late in March and very early in May. This indicated that premature budding under night-break conditions may occur more in late summer to autumn than in early summer. Therefore, we selected summer-to-autumn-flowering small-flowered chrysanthemum cultivars whose flower initiation is inhibited by night-break until cropping on the day of the autumn equinox in September in Okayama Prefecture. Several cultivars that showed later budding than the summer-to-autumn-flowering standard-type chrysanthemum cultivar 'Sei-un' used in light culture were selected for the fine control of flowering using light culture. We confirmed and evaluated the utility of these selected cultivars for flowering control using light culture in Fukushima, Akita and Ibaraki Prefectures. Although the flowering time of the selected cultivars varied among prefectures under natural daylength conditions, fine control of the flowering time was established using light culture. These results show that the method developed in this study is useful for selecting summer-to-autumn-flowering small-flowered chrysanthemum cultivars suitable for the fine control of flowering by using light culture.

本論文では,画像共有サービスに投稿される画像の観光名所に関するカテゴリー(観光カテゴリー)の分類手法を提案する.提案手法では,画像共有サービスにおいて画像とともに投稿される様々なデータの中で,位置座標が観光カテゴリーの分類に最も効果的であることに注目する.更に,このデータに基づいた分類において誤りが発生する場合を,分類結果から導出される確信度に基づいて判定する.誤分類と判定された場合,提案手法では,画像及びタグの特徴に基づいた分類結果を求め,それらを各々の分類精度に注目して統合することで,最終的な分類結果を高精度に推定可能とする.このとき,位置座標による分類結果に基づいて分類候補の観光カテゴリーを限定することで,多クラス分類問題におけるクラス数を減少させ,より正確な分類を可能とする.以上の提案手法によって,異なる種類のデータの分類精度が互いに大きく異なる場合に従来手法では困難であった高精度な最終分類結果の取得が可能となる., IEICE, the Institute of Electronics, Information and Communication Engineers, Japanese - Efficiency of a Dynamic Ice Storage System

本論文では,走査型電子顕微鏡(Scanning Electron Microscop,SEM)で撮像された画像を用いた生物の分類法を提案する.提案手法では,生物学者が構築した分類体系に注目し,各ノードにその下位のノードへの分類を行う分類器を割り当てることで,決定木を構築する.これにより,構築された決定木を用いて生物の分類が可能となる.このように,生物の分類に有用な分類体系の構造を導入することで,画像特徴のみに注目する生物の分類法と比較して,高精度な分類が期待できる.また,提案手法では,更なる精度向上のため,以下の二つの処理も導入する.まず,分類体系において,画像特徴が類似する異なるノードに注目した決定木の変更を行い,誤分類を抑制する.次に,同種の生物の異なる撮像倍率の画像に対し,モーフィングを施すことで学習データの充足を行う.以上によって,提案手法では,SEMで撮像された生物の高精度な分類が可能となる.本論文の最後では,提案手法の有効性を確認するための実験結果を示す., 電子情報通信学会, Japanese - A note on Web video retrieval based on network structure analysis using video features and tag information : Retrieval performance improvement using local learning regularization

以前,我々は,映像の類似したショットが隣接せずに出現する構造(映像の構造)に注目したシーン分割手法を提案した.しかしながら,映像の構造に注目したシーン分割手法の共通の問題として,映像の構造を取得する際に用いられるシーンの最長時間幅の設定が困難であるという点が存在した.そこで,本論文では,その改良手法として映像の構造に注目したMCMC法に基づくシーン分割手法を提案する.提案手法では,シーンの最長時間幅を変化させて映像の構造に基づき取得された全ての境界をシーン境界候補とし,それらの中からMCMC法に基づいて最適なシーン境界を推定する.これにより,従来の手法を適用する際に設定が困難であったシーンの最長時間幅を一意に決定することなく,MCMC法により最適なシーン境界を求めることが可能となる.本論文の最後では,実際にテレビで放送された映像に対して提案手法を適用し,その有効性を確認する., 一般社団法人電子情報通信学会, Japanese - 映像の構造に注目したMCMC法に基づくシーン分割法

本論文では,エッジの連続性を考慮した, Iterated Function System (IFS)に基づく画像拡大法を提案する.従来のIFS画像拡大法では,拡大後の画像において処理の最小単位となるブロックの境界で,本来存在しないはずの輝度値の変化が生じる.また,エッジの連続性を考慮しておらず,拡大後の画像におけるエッジが不連続となる問題が存在した.そこで提案手法では,まず,処理の最小単位となるブロックの重なりを許すことで, IFSによる高近似縮小写像を実現し,ブロック境界での輝度値の変化を抑制する.更に,連続性を保ったエッジの推定が可能であるラインプロセスを新たにIFS画像拡大法に導入する.このとき我々は,ラインプロセスを拡大後の画像のエッジを推定する手法に拡張することで,輝度値が未知である拡大後の画像に対しても,連続性を保ったエッジの推定を可能とする.また,提案手法では得られるエッジの存在を考慮した上でIFSに基づく画像拡大を行うことにより,従来法で発生していた拡大後の画像におけるエッジの不連続を解決し,高精細な拡大を実現する.本論文の最後では,提案手法の有効性を示すため比較実験を行い,その拡大性能を評価する., 一般社団法人電子情報通信学会, Japanese - A Note on Extension of Particle Filter : Application for Flow Estimation of Image Sequence

This paper extends a particle filter and applies it for a flow estimation method based on a Helmholtz decomposition theorem. The proposed method utilizes a state transition model including two state variables affecting each other and an observation model affected by a previous observation. These models do not satisfy traditional particle filter's assumptions that the current state variable depends only on itself at the previous time and the current observation depends only on the current state variable.

This paper proposes an effective flow estimation method based on a Helmholtz decomposition theorem with a particle filter. In a traditional method based on the Helmholtz decomposition theorem, since it does not consider translation and estimation errors included in previous flows, its performance tends to become degraded. Therefore, the proposed method extends the Helmholtz decomposition theorem with the translation. By using the extended theorem, the flow estimation considering the translation can be realized.

OGAWA Takahiro, HASEYAMA Miki, Technical report of IEICE. VLD, 106, 114, 7, 12, 16 Jun. 2006
This paper proposes an accurate reconstruction method of missing textures in still images using an ER algorithm.

本論文では,GMRFモデルを用いた静止画像における失われた輝度値の復元手法を提案する.画像中に存在する輝度値消失領域を高精度に復元するためには,エッジ部を精度良く再構成する必要がある.そこで,我々はGMRFモデルを用いて,特に失われたエッジ部を高精変に復元する手法の実現を試みる.このとき,提案手法において用いられるGMRFモデルは,画像が複数の領域により構成され,各領域は弱定常な確率過程であるという仮定のもとで導出される.したがって,提案手法のモデルは画像中の異なる領域間でエッジの表現が可能となり,エッジ部において高精度な復元結果を与える.更に,・このモデルは輝度値消失領域に複数の領域が合まれ,それらが複数のエッジを構成する場合についても,その適用が可能であり,このような場合に従来手法が抱えていた問題である再構成されたエッジ部の過剰な平滑化が抑制される.本論文の最後では,提案手法の有効性を示すために実画像を用いた比較実験を行い,エッジ部における復元性能を評価する., 一般社団法人電子情報通信学会, Japanese - Image Recognition Method Using Intensity Gradient Vectors

This paper proposes an image clustering method which includes an automatic cluster-number setting scheme. By using the proposed method, the user can effectively categorize similar images existing in an image database without presetting the total number of categories. Actually, the proposed method is based on a k-means algorithm which utilizes a color histogram of each image as a feature vector, and the number of the cluster is determined, according to the variation of the average of the clustering error in several number of the clusters. Consequently, the proposed method can automatically select the suitable number of the clusters for the image database, and then it provides the accurate image clustering result. Some experimental results show the proposed method achieves accurate clusterings., The Institute of Electronics, Information and Communication Engineers, English - AN IMAGE ENLARGEMENT METHOD USING ITERATED FUNCTION SYSTEM

This paper proposes an effective image enlargement method based on an Iterated Function System (IFS), which is well-known as an image coding method. The IFS can reconstruct an image of a different size from the coding target image's. Based on this property, this paper expands the IFS for coding to a method for the image enlargement. However, if the IFS is simply expanded for the image enlargement use, it cannot achieve accurate enlargement. For example, the block-wised procedures of the IFS make a problem that the enlarged images suffer from block noise. Therefore, the proposed method is realized by not only the expansion but also some modifications. Some simulation results are shown to verify that the performance of the proposed method is higher than that of the conventional methods., The Institute of Electronics, Information and Communication Engineers, English - 静止画像中に存在する消失テクスチャの再構成に関する検討―ERアルゴリズムにおける拘束条件の考察―

Several methods for reconstruction of missing textures in still images have been studied. However, they cannot restore the missing areas without suffering from degradations, so that their performance is not enough for accurate restoration. Therefore, this paper proposes an accurate reconstruction method using the ER (Error-Reduction) algorithm. Noting a feature of texture images, the proposed method can calculate the Fourier transform magnitude of the area including missing pixels from the area whose texture is similar in the target image. The similar texture is selected by a novel approach monitoring the errors of the ER algorithm. Further, the proposed method recovers the phase of the target area from the obtained Fourier transform magnitude by using the ER algorithm modified for the restoration and can accurately reconstruct the missing textures. Some experimental results are shown to verify its high performance of the proposed method., 映像情報メディア学会, Japanese - A study on reconstruction of missing texture in still images Application of ER algorithm

論文では,オプティカルフローを用いた静止画像の輝度値の高精度な復元手法を提案する.画像の失われた輝度値の復元において,エッジ部を正確に再構成することは重要な課題である.そこで本論文では,従来より動画像の動き解析に利用されているオプティカルフローを,静止画像に適用可能な形に変更し,これを用いることで輝度値の高精度な復元を行う.また,より高精度な推定輝度値を与えるオプティカルフローを算出するために,提案手法では画素間の輝度値の相関に着眼した新たな指標を導入する.この指標を用いて算出されるオプティカルフローは輝度値が失われた画素の近傍に存在する画素から,より真の輝度値に類似した画素を選択することを可能とし,輝度値が大きく異なる画素の影響を受けずに復元できる.これにより,特にエッジ部分における復元精度が向上するだけでなく,従来の復元手法では困難であった輝度値の失われた領域を複数のエッジが通過する場合や,通過するエッジの方向がその領域内で大きく変化する場合にも,正確に失われたエッジの再構成を行うことが可能となる.本論文の最後では実験を行い,提案手法の有効性を示す., 一般社団法人電子情報通信学会, Japanese - A Study on Restoration of Missing Areas Application of GMRF Model

画像診断支援を目的とした人工知能(AI)は目覚ましい発展を続けている。多くの論文は特定の疾患の診断がAIによって実現できたことを成果としている一方で、日常診療における画像診断では、特定の疾患に限定されるのではなく、多臓器・多疾患をカバーする必要がある。現在の画像診断AI研究の主流は、画像を入力とし、病態を考えるプロセスをバイパスして診断に至る方式を取っており、この方法では各疾患に対応したAIを個別に開発する必要があるため、汎用的なAIの完成までに時間がかかる。本研究は、既存の戦略に対する新たなアプローチとして、人間の思考プロセスを模倣し既存のAIに欠くロジカルシンキング(論理的思考)を取り入れる。すなわち、医師が画像診断を行うときと同様に、異常所見の場所と性状に加えて、患者背景の情報を明らかにした上で、総合的に結論を出すAIの構築を目指す。この目的のため、多施設から得られる数万件のFDG-PET/CTの画像とレポートの組と、ナショナル・データベースであるJ-MIDの画像とレポートの組、そして画像解析と自然言語処理を融合するAI技術を使用する。
R5年度の主な成果は3つである。①異常所見を検出した後に解剖学的な部位を明らかにするための基盤技術となる非剛体変形アルゴリズムの開発と精度評価を行った。6パラメーターのアフィン変換および多パラメーターからなる変形場を用いる方法を評価し、一定の傾向を見出した。②本研究では異常所見の検出に正常例のみを学習に用いる予定であるため、normal database構築のために画像診断医が異常なしと診断した症例の抽出を開始した。③公開された画像診断レポートに対してlarge language model (LLM)を用いて主病変や転移の有無などの情報を抽出し、LLMやプロンプトを変化させた際の性能変化について検討し、一定の傾向を見出した。

We studied low-computation and memory-saving convolutional sparse representation techniques. Specifically, by making the sparse representation coefficients binary, we constructed "sparse approximation based on nearest neighbor basis search" and "dictionary learning based only on simple addition" to realize convolutional sparse representation with low computational complexity. In addition, we newly constructed a "self-organizing dictionary learning technique" focusing on the principle of iterative function systems, and realized memory-saving dictionary learning. Our study has a large ripple effect since it will lead to breakthroughs in all application fields using sparse representation. Furthermore, our technology can contribute to technologies such as image/video coding, restoration, and super-resolution on various terminals.

This study constructed a new theory for deriving super-versatility cross-media bases to break limitations in various research fields related to image processing such as image coding, restoration, recognition, retrieval and recommendation, etc. Specifically, by collaboratively analyzing both of image data and their corresponding semantic information, sematic analysis of each area in images was realized to simultaneously derive new bases for their optimal approximation. Since these bases included high versatilities, they could be applied to various kinds of research fields related to image processing, and the performance improvement were realized. Therefore, in this study, we actually confirmed that our new approach provided breakthroughs for each research field by using the derived cross-media bases.

Based on the obtained model, systems for creating new types of multimedia contents were realized. Furthermore, new multimedia recommendation frameworks were newly constructed, and these frameworks could realize mutual recommendation through the use of the above systems by multiple users. Finally, we performed demonstration experiments of these frameworks in various fields and verified their performance.

Biologists of this team accumulated more than 30,000 datasets, composed of SEM photos and text data on insects, birds or fishes. Information scientists built a biomimetic image retrieval system supported by ontology. This system is opened to the public through the internet. Outreach activities including an exhibition on biomimetics in the National Museum of Nature and Science, Tokyo (April-June 2016) were carried out. A book on biomimetics for general public was published in March 2016.

In this study, we realized algorithms for accurate high-quality image reconstruction based on representation bases obtained from training images in databases. Specifically, we realized 1) simultaneous removal of multiple degradation elements, 2) derivation of representation bases for obtaining high-quality images and 3) selection scheme of optimal bases suitable for reconstructing target contents. Consequently, our study improved the performance limitation existing in the field of image restoration such as error concealment, noise removal and super-resolution.

We implemented an effective method for recommending the desired contents to a user. The method accepts an image, video or music clip as a query, and is based on search theory that can deal with ambiguous user requests that are unique to each image, video or music clip. Specifically, in order to implement this method, we narrow down the search results to the three media types of image, video and audio, and implement cross-media search, allowing the user to acquire the desired contents even in cases where they cannot express the same query using keywords or media of the identical type.

これまで欠落領域の復元に用いてきたアルゴリズムを、画像の高解像度化、および類似画像検索のための画像の意味的特徴量の推定に応用を行った。まず、画像の高解像度化では、これまで提案を行ってきたカーネル主成分分析に基づいた失われた情報の推定法を応用し、既知の情報を低解像度画像における低周波成分、未知の情報を本来高解像度画像が有していたはずの高周波成分に置き換えることで、失われた高周波成分の推定を可能とした。近年の単一フレームによる超解像手法では、失われた高周波成分を推定するために、教師データとなる高解像度画像が必要となるのに対して、我々の研究では画像の異なる階層間での相関を用いることで、教師データを用いずに失われた高周波成分の推定が可能であり、非常に有効であることが確認された。
さらに、我々は画像の高解像度化への応用だけでなく、復元や再構成とは異なる分野である類似画像検索への応用も試みた。一般に、対象となる画像に対して高精度に類似画像検索を行うためには、単純に画像特徴量間で距離を求めるのではなく、画像特徴量から意味的特徴量を推定し、それらの間で距離を求める手法が必要となる。我々はカーネル主成分分析を用いた画像の意味的特徴量の推定手法を提案し、与えられる画像の画像特徴量から意味的特徴量を高精度に推定することを可能とした。これにより、得られる意味的特徴量を用いることで、従来では困難であった画像内容に基づく類似画像検索を行うことが可能となった。このように、我々は復元・再構成の分野だけでなく、近年発展の著しい検索の分野への新たなアプローチの提案も行ってきた。
