Abstract
A method of image analysis, includes: obtaining a sequence () of images, each represented by pixel data; performing a vision-based analysis on at least one of the sequence () of images to obtain data for classifying a state of a subject represented in the images;—determining at least one value of a physiological parameter of a living being represented in at least some of the sequence () of images; and classifying a state of the subject using the data obtained with the vision-based analysis and the at least one value of the physiological parameter. The at least one value of the physiological parameter is determined through analysis of image data from the same sequence () of images from which the at least one image on which the vision-based analysis is performed is taken. A method of enabling remote photoplethysmographic analysis includes: obtaining a sequence () of images from at least one camera (), 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 (), providing a signal representative of at least variations in a time-varying value of a combination of pixel values at least a number of image points in the measurement zone () for use in determining at least one value of a physiological parameter. At least part of a selected subject represented in the sequence () of images is tracked, and a directable light source () illuminating at least part of the selected subject is controlled.
