New MEDN Network Decouples Motion and Emotion for Micro-Expression Recognition

Researchers have developed a new Motion-Emotion Feature Decoupling Network (MEDN) to improve micro-expression recognition. This network addresses the challenge that micro-expressions can have similar facial action units but convey opposite emotions. MEDN uses a dual-branch framework to separately extract motion and emotion features, with a Sparse Emotion Vision Transformer (SEVit) for implicit emotion modeling and a Collaborative Fusion Module (CoFM) to adaptively merge these disentangled features. Experiments on benchmark datasets show that MEDN achieves superior recognition performance and generalization. AI

IMPACT This research offers a novel approach to micro-expression recognition by disentangling motion and emotion features, potentially improving accuracy in AI systems that analyze subtle facial cues.

    MEDN: Motion-Emotion Feature Decoupling Network for Micro-Expression Recognition

    arXiv:2604.17899v2 Announce Type: replace Abstract: Unlike macro-expression, micro-expression does not follow a strictly consistent mapping rule between emotions and Action Units (AUs). As a result, some micro-expressions share identical AUs yet represent completely opposite emot…
