= SYSTEM AND METHOD UTILIZING OPTICAL DEPTH SENSOR FOR RECOVERING CARDIAC PULSE FROM CHEST MOTION IN DEPTH VIDEOS =

'''Abstract''':
a system and method utilizes optical depth sensors to estimate heart rate of one or more subjects. a method includes obtaining optical depth video data of at least one subject; identifying a region of interest of the subject(s) from optical depth video data; segmenting the region of interest into multiple areas; identifying pixel intensity with respect to time in the areas to produce a depth signal data matrix including multiple spatial channels; decomposing the depth signal data matrix into a low-rank spatial-temporal eigenvector matrix to produce refined depth signal data streams; and projecting the refined depth signal data streams onto a selected pulsatile direction and producing a cardiac pulse signal for the subject(s).
