Residual Flow Matching with Dynamic Cross-Interaction for 3D Multi-Person Motion Prediction

A Prior-Guided Residual Flow Matching framework for 3D multi-person motion prediction that establishes a kinematic anchor and temporally synchronizes inter-agent message-passing with the integration progress, ensuring the extraction of reliable social contexts and improving multi-person motion fidelity.
