Abstract :
A new image sequence coding scheme based on the multiresolution tree structure is proposed. It not only guarantees reliable and homogeneous motion field, but also reduces the amount of computation necessary in the motion vector search. With nearly the same decoded image quality, 25-30% bit rate reduction can be obtained compared with the MPEG-I algorithm.<>
