We propose a novel approach to human facial expression recognition using only the shape information at a finite set of fiducial points, extracted from the 3D neutral and expressive faces. In the course of applying the technique to the facial database, BU-3DFE, which contains facial shape and 2D color (‘‘texture”) information, we extract from the images of neutral and expressive faces, salient contours in the facial interestregions around the eyebrows, eyes, nose and mouth by invoking an active… CONTINUE READING
