Researchers have developed a new spatial-temporal transformer framework designed to improve heart-rate estimation for robots using cameras. This system is specifically engineered to be robust against varying illumination conditions, a common challenge for remote photoplethysmography (rPPG) technology. The framework integrates advanced techniques like 3D face alignment and clip-level illumination augmentation, achieving a mean absolute error of 0.79 bpm and a correlation of 0.982 in experiments. AI
