The authors describe a variable block-size motion estimation scheme that improves the motion estimation performance by subdividing blocks of images into subblocks and estimating their movements. The variable block-size technique is applied to encode the motion-compensated interframe differential pels in both the transform domain and the pel-domain coding. Simulation results demonstrate that both transform-domain and pel-domain coding algorithms benefit from the variable block-size (VBS) approach, and a pel-domain algorithm performs almost as well as a DST (discrete sine transform) algorithm when the VBS approach is used.
