Claim Text:
1. A method for compensating for motion induced artifacts in physiological signals obtained from a single video captured by a single video imaging device of a subject being monitored for a desired physiological function in a non-contact, remote sensing environment, the method comprising: receiving a video comprising a plurality of time-sequential image frames captured by a video imaging device of at least a first and second region of interest of a subject being monitored for a desired physiological function, said first region being an area of exposed skin wherein a desired signal corresponding to said physiological function can be registered by the video imaging device, said second region being an area where a movement by said subject is likely to induce motion artifacts into said signal; processing said video to isolate pixels in said image frames associated with each of said first and second regions of interest; processing pixels of said isolated first region to generate a time-series signal; extracting, from said time-series signal, a physiological signal corresponding to said desired physiological function; analyzing pixels of said isolated second region to identify time intervals when movement by said subject has occurred; and for each of said identified time intervals when movement has occurred:
