Apex-Centered Spatio-Temporal Rank Pooling and Gradient Attention for Micro-Expression Recognition 事件

Apex-Centered Spatio-Temporal Rank Pooling and Gradient Attention for Micro-Expression Recognition arXiv:2509.00056v3 Announce Type: replace Abstract: Micro-expression recognition (MER) is a challenging task due to the subtle and fleeting nature of micro-expressions. Traditional input modalities, such as Apex Frame, Optical Flow, and Dynamic Image, often fail to adequately capture these brief facial movements, resulting in suboptimal performance. In this study, we introduce the Micro-expression
