Template Collapse and Information-Theoretic Limits in Camera rPPG Pulse Morphology Restoration 事件

Template Collapse and Information-Theoretic Limits in Camera rPPG Pulse Morphology Restoration arXiv:2606.03802v1 Announce Type: new Abstract: Objective: Consumer face camera remote photoplethysmography (rPPG) enables passive cardiovascular monitoring, but whether single-cycle waveform morphology encoding arterial stiffness biomarkers is recoverable from this measurement has not been characterised. Methods: We evaluated 16 architectures spanning six families on 153 subjects across three datas
