Abstract

Abstract

This paper presents an algorithm for video signal coding based on 3D-wavelet transformation. When the frame order t of the video signal is replaced by order z,the video signal can be looked as a block in the 3D-space. After split the block into smaller sub-blocks,imitate the method of 2D-wavelet transformation for image, the sub-blocks can be transformed with 3D-wavelet. Most of the video signal energy is in the transformed low-frequency bands.These bands affected the visual quality of the video signal most. After quantizing different bandswith different precision and entropy coding each band, the inter- and intra-frame redundancies of the video signal can be eliminated and the data can be compressed. The simulation experiments show that this algorithm can achieve very good result.
