摘要：
A remote photoplethysmography (RPPG) system includes an input interface to receive a sequence of measurements of intensities of different regions of a skin of a person indicative of vital signs of the person； a solver to solve an optimization problem to determine frequency coefficients of photoplethysmographic waveforms corresponding to the measured intensities at the different regions, wherein the solver determines the frequency coefficients to reduce a distance between intensities of the skin reconstructed from the frequency coefficients and the corresponding measured intensities of the skin while enforcing joint sparsity on the frequency coefficients； and an estimator to estimate the vital signs of the person from the determined frequency coefficients of photoplethysmographic waveforms.
