【Abstract】 Video technology is a key to multimedia storage and transmission. A technique of video compression based on 3D wavelet transform and motion compensation is proposed. With this algorithm, the image is firstly decomposed by three scale wavelet transform, then the coding method is applied to different frequency sub band images and thus the redundant information is eliminated with motion compensation. The experimental results with artificial and real data are given.更多还原
