Abstract
A method of processing images of at least one living being, includes obtaining a sequence () of digital images taken at consecutive points in time. At least one measurement zone () comprising a plurality of image points is selected. For each measurement zone (), a signal () representative of at least variations in a time-varying value of a combination of pixel values at at least a number of the image points for use in determining at least one of a presence and a frequency value of at least one peak in a spectrum of the signal () corresponding to a frequency of a periodic physiological phenomenon is obtained. The step () of selecting at least one measurement zone () includes analyzing information based on pixel data of a plurality of image parts in at least one of the images (), each image part including at least one image point, and selecting each measurement zone () from contiguous parts determined to have similar characteristics.
