Abstract :
MPEG-21 describes the multimedia framework for us in the near future. And the basic unit, digital item (DI), which will encapsulate and unify the operation for the multimedia application, is proposed in MPEG-21. Color images are embodied in three different frames and it is not enough to utilize color redundant information in traditional compression methods. To exploit the hue redundancy in compressing color image fully, the method based on 3D submatrix integration transform (SIT) is proposed in MPEG-21 in this paper. The experimental results show that the method proves to be effectual in compression efficiency and will provide good compatibility under the context of MPEG-21
