Abstract :
To reduce the temporal redundancy in video frame sequence for the similarity between the current and the prior image, a new video coding algorithm based on zero-tree wavelet with extremely high compression is presented in this paper. A new scheme is presented which employs adaptive strategy based on different motion detected in frame sequence. With the algorithm we have realized the real-time compression of video streams with high fidelity.
