However, previous methods have two critical issues: first, spatial dependencies for distal joints in each independent frame are hard to learn; second, the basic architecture of graph convolution network ignores hierarchical structure and diverse motion patterns of different body parts. To address these issues, this paper proposes an intra-frame skeleton constraints modeling method and a Grouping based Multi-Scale Graph Convolution Network (GMS-GCN) model. The intra-frame skeleton constraints modeling method leverages self-attention mechanism and a designed adjacency matrix to model the skeleton constraints of distal joints in each independent frame. The GMS-GCN utilizes a grouping strategy to learn the dynamics of various body parts separately. Instead of mapping features in the same feature space, GMS-GCN extracts human body features in different dimensions by up-sample and down-sample GCN layers. Experiment results demonstrate that our method achieves an average MPJPE of 34.7mm for short-term prediction and 93.2mm for long-term prediction and both outperform the state-of-the-art approaches.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"353 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122791411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As most STR approaches focus on English, we consider both English and Chinese as Chinese is also a major language, and it is a common scene in many areas/countries where both languages can be seen. The OGT consists of an Outline Generator (OG) and a transformer with a language model embedded. The OG detects the character outline of the text and embeds the outline features into a transformer with the outline-query cross-attention layer to better locate each character and enhance the text recognition performance. The training of OGT has two phases, one is training on synthetic data where the text outline masks are made available, followed by the other training on real data where the text outline masks can only be estimated. The proposed OGT is evaluated on several benchmark datasets and compared with state-of-the-art methods.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126492214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, interpreting X-rays can be time-consuming, subjective, prone to error, and requires specialized knowledge. Automated segmentation methods using AI can improve interpretation and aid in diagnosis and patient education. Our U-Net model, trained on 344 bitewing and periapical X-rays, can identify two pathologies and eight anatomical features. It achieves an overall diagnostic performance of 0.794 and 0.787 in terms of Dice score and sensitivity, respectively, 0.493 and 0.405 for dental caries, and 0.471 and 0.44 for root infections.

Creating new 360°-specific datasets and training recognition models for each domain and tasks have a significant barrier for many users aiming at practical applications. Therefore, we propose a novel technique to effectively adapt the existing models to 360° images. The 360° images are projected to multiple planes and adapted to the existing model, and the detected results are unified in a spherical coordinate system.

The minute defects on the display surface are hard to spot out in RGB images and by a model trained with only normal data. To address this, we propose a novel contrastive learning scheme for knowledge distillation-based anomaly detection. In our framework, Multiresolution Knowledge Distillation (MKD) is adopted as a baseline, which operates by measuring feature similarities between the teacher and student networks. Based on MKD, we propose a novel contrastive learning method, namely Multiresolution Contrastive Distillation (MCD), which does not require positive/negative pairs with an anchor but operates by pulling/pushing the distance between the teacher and student features. Furthermore, we propose the blending module that transforms and aggregate multi-channel information to the three-channel input layer of MCD. Our proposed method significantly outperforms competitive state-of-the-art methods in both AUROC and accuracy metrics on the collected Multi-illumination and Multi-focus display image dataset for Anomaly Detection (MMdAD).","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129295108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individual identification is fundamental to traceability, documentation, and optimization for patient safety, compliance, economy, and the environment. However, existing identification systems have yet to be adopted by most hospitals due to the costs and risks of tagging or marking. The \"Fingerprint of Things\" recognition technology enables tag-less identification; however, scanning automation to save labor costs, which should be devoted to patient care, is also essential for practical use. We developed a new system concept that automates the detection, type recognition, fingerprint scanning, and identification of every instrument in the workspace.
