Camera-based pulse monitoring lacks individual arterial morphology recovery

A new research paper published on arXiv explores the limitations of using consumer-grade cameras for remote photoplethysmography (rPPG) to assess cardiovascular health. The study evaluated 16 different AI architectures and found that none could reliably recover subject-specific arterial pulse morphology from single-cycle rPPG signals. Researchers concluded that current camera technology is insufficient for encoding individual arterial stiffness biomarkers, and proposed cross-subject correlation as a critical diagnostic for waveform reconstruction benchmarks.
