Researchers have introduced a novel self-supervised learning paradigm called Physiological Causal Probing (PCP) to improve the accuracy of remote photoplethysmography (rPPG) measurements. Existing methods often learn spurious correlations with noise rather than the true physiological signal. PCP addresses this by actively intervening on video data based on a hypothesized rPPG signal and verifying if the outcomes align with physical expectations, thereby mitigating artifacts from motion and illumination.
