AUTOMATIC FACE AND FACIAL FEATURE LOCATION DETECTION FOR LOW BIT RATE MODEL-ASSISTED H.261 COMPATIBLE CODING OF VIDEO

摘要

An apparatus responds to a video signal representing a succession offrames, where at least one of the frames corresponds to an image of an object, todetect at least a region of the object. The apparatus includes a processor forprocessing the video signal to detect at least the region of the object characterizedby at least a portion of a closed curve and to generate a plurality of parametersassociated with the closed curve for use in coding the video signal.
