Noise-resilient spatial–channel refinement for robust remote photoplethysmography

IntroductionRemote photoplethysmography (rPPG) enables non-contact heart rate measurement from facial videos with growing health monitoring applications. Despite advances in deep learning methods, most existing approaches lack task-specific feature refinement across spatial and channel dimensions, w...
