DOSE: Dominance-Guided Ordinal Severity Estimation from Sparse Relative Annotations
Tushir Sahu, Hideaki Hayashi, Hajime Nagahara
Medical severity estimation commonly relies on absolute grade annotations, which are fundamentally ordinal, yet existing methods often treat the grades as independent categories. L…
Exploring the Latent Structure of AMD Severity Using Retinal Foundation Models
Niccolò Fineschi, Jovana Panic, Atsushi Watanabe +7
Retinal foundation models have demonstrated strong performance across a wide range of ophthalmic tasks, yet relatively little is known about how disease-related information is repr…
Point-Supervised Facial Expression Spotting with Gaussian-Based Instance-Adaptive Intensity Modeling
Yicheng Deng, Hideaki Hayashi, Hajime Nagahara
Automatic facial expression spotting, which aims to identify facial expression instances in untrimmed videos, is crucial for facial expression analysis. Existing methods primarily…
Enhancing Ambiguous Dynamic Facial Expression Recognition with Soft Label-based Data Augmentation
Ryosuke Kawamura, Hideaki Hayashi, Shunsuke Otake +2
Dynamic facial expression recognition (DFER) is a task that estimates emotions from facial expression video sequences. For practical applications, accurately recognizing ambiguous…
CALICO: Confident Active Learning with Integrated Calibration
Lorenzo S. Querol, Hajime Nagahara, Hideaki Hayashi
The growing use of deep learning in safety-critical applications, such as medical imaging, has raised concerns about limited labeled data, where this demand is amplified as model c…
SpotFormer: Multi-Scale Spatio-Temporal Transformer for Facial Expression Spotting
Yicheng Deng, Hideaki Hayashi, Hajime Nagahara
Facial expression spotting, identifying periods where facial expressions occur in a video, is a significant yet challenging task in facial expression analysis. The issues of irrele…
Multi-Scale Spatio-Temporal Graph Convolutional Network for Facial Expression Spotting
Yicheng Deng, Hideaki Hayashi, Hajime Nagahara
Facial expression spotting is a significant but challenging task in facial expression analysis. The accuracy of expression spotting is affected not only by irrelevant facial moveme…
