PhysAgent: A Multi-Agent Framework for Reliable Remote Heart Rate Estimation

Yehui Yang, Bo Zhao, Junzhe Cao +4

Remote photoplethysmography (rPPG) enables non-contact heart-rate estimation from facial videos, but its weak physiological signal is easily corrupted by motion, illumination chang…

AffectAgent: Collaborative Multi-Agent Reasoning for Retrieval-Augmented Multimodal Emotion Recognition

Zeheng Wang, Zitong Yu, Yijie Zhu +9

LLM-based multimodal emotion recognition relies on static parametric memory and often hallucinates when interpreting nuanced affective states. In this paper, given that single-roun…
