Patent attributes
What is disclosed is a system for compensating for motion induced artifacts in a physiological signal obtained from multiple videos of a first and second region of interest a subject being monitored for a desired physiological function. At least one of the videos being of the first region and at least one of the videos being of the second region. The first region being at least one area of exposed skin where a desired signal corresponding to the physiological function can be registered by a video imaging device. The second region being an area where a movement by the subject is likely to induce motion artifacts into the signal. The videos are processed to isolate pixels associated with the first and second regions. Processed pixels of the isolated first regions to obtain a composite time-series signal. From the composite signal, a physiological signal corresponding to the physiological function is extracted.
