Estimating the term…
A system and method for PPG analysis processes images to determine PPG signals from different image regions of the images and determine relative delays between the PPG signals for the different image regions. The time alignment between the PPG signals is improved so that a more accurate global PPG signal is obtained for the overall region of interest. In this way, PPG signals are realigned or partially realigned to provide an overall PPG signal with improved signal to noise ratio.
A system, comprising a processor adapted to receive images of a region of interest and to process the images to:
A computer-implemented method for processing images to derive remote PPG signals, comprising:
