Adaptive Physical-Facial Representation Fusion via Subject-Invariant Cross-Modal Prompt Tuning for Video-Based Emotion Recognition
A subject-invariant cross-modal prompt-tuning method with decoupled shared-specific adapters fuses facial and rPPG features in a frozen ViT to improve video-based emotion recognition accuracy and cross-subject generalization on MAHNOB-HCI and DEAP.
