Abstract

A block-based motion model capable of determining velocity and orientation of motion of a sequence is developed in this paper. Based on the model, three classes of motion orientation, namely horizontal, vertical and diagonal motion in the velocity range of 1 - 8 pixels/frame, are identified. The classification is valuable in coding whereby a reduced motion search is adequate to obtain the best prediction. A low-complexity motion detection scheme is also considered here which takes advantage of the 3D subband decomposition architecture employed.
