METHOD AND SYSTEM FOR IMAGE ANALYSIS

A method of enabling remote photoplethysmographic analysis includes: - obtaining a sequence (37;51) of images from at least one camera (3), each represented by pixel data representative of reflected ambient light in at least a limited range of wavelengths; and, - for at least one measurement zone (4...

Summary:A method of enabling remote photoplethysmographic analysis includes: - obtaining a sequence (37;51) of images from at least one camera (3), each represented by pixel data representative of reflected ambient light in at least a limited range of wavelengths; and, - for at least one measurement zone (41), providing a signal representative of at least variations in a time-varying value of a combination of pixel values at at least a number of image points in the measurement zone (41) for use in determining at least one value of a physiological parameter. At least part of a selected subject represented in the sequence (37;51) of images is tracked, and a directable light source (4) illuminating at least part of the selected subject is controlled.
