摘要： The present invention relates to a video encoding device (10, 10', 10'') and method for encoding video data and to a corresponding video decoding device (60, 60') and method. To preserve PPG relevant information after encoding without requiring a large amount of additional data for the video encoder output stream, the proposed video encoding device comprises a selection unit (20, 20') for selecting a region of interest (101) in input video data (100) providing a strong PPG signal, a first encoding unit (30,30') for encoding said selected region of interest (101) of said input video data (100) according to a predetermined encoding scheme with a first setting of the encoding to preserve PPG-relevant information in the encoded region of interest, a second encoding unit (40, 40') for encoding remaining parts (103) of said input video data (100) according to said predetermined encoding scheme with a second setting of the encoding, and an encoder combination unit (50) for combining the encoded region of interest (102) and the encoded remaining parts (104) of said input video data into an encoder output video stream (105).

摘要： A method of image analysis, includes: obtaining a sequence (37;51) of images, each represented by pixel data; performing a vision-based analysis on at least one of the sequence (37;51) 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 (37;51) 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 (37;51) 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 (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.
