CodePhys: Robust Video-based Remote Physiological Measurement through Latent Codebook Querying
CodePhys casts remote heart-rate measurement as a code query task: a video encoder produces features matched to a learned codebook of clean PPG waveforms, and a pre-trained decoder reconstructs the pulse.
