摘要

Lossless compression of video is an important problem in multimedia applications such as telemedicine and satellite imagery. Hence a need arises to optimize storage and transmission bandwidth. In this paper, we present the several experiments conducted to compress each frame of a video sequence by optimizing different parameters in an EZW framework. Compression efficiencies for the football video sequence consisting of 60 frames are tabulated
