STAG: Spatio-temporal Evolving Structural Representation of Action Units for Micro-expression Recognition

Nandani Sharma, Varun Sharma, Dinesh Singh

Micro-expression recognition is challenging due to subtle and short-lived facial muscle movements. Existing methods rely heavily on apex-onset frames, overlook fine-grained inter-frame dynamics, and separately model spatial and temporal information, limiting generalization across…Read more
