Abstract :
Segmentation-based motion compensation is used in combination with adaptive wavelet packet transform for compressing image sequences. Motion compensation and estimation are performed at both encoder and decoder so that the region shape information need not be transmitted and only the changed vectors are transmitted. This is very useful in low bit-rate applications. Also the adaptive wavelet packet transform used promises a very faithful representation of the images
