Could you build this?
No Real-time photoplethysmography (rPPG) from webcam video requires specialized computer vision, signal processing, and physiological modeling expertise.
What it would actually take: The stack involves browser-based WebAssembly/WebGL models for facial landmark tracking, extracting spatial RGB pixel variation over the skin, filtering environmental noise using signal processing algorithms (like POS or CHROM rPPG pipelines), and running fast Fourier transforms (FFT) or bandpass filters to isolate heart rate variations. Building robust rPPG that accounts for diverse skin tones, motion artifacts, and lighting fluctuations requires specialized biomedical signal processing domain expertise.
