摘要
研究了向量小波在活动图像数据压缩中的应用．利用序列图像中相邻两帧之间数据无多大变化的特点，改进了重复行预滤波方法，采取相邻两帧重复行方法，获得了较高的分解、重构速度；由于采取了适当的量化与编码，在图像质量主观评价好的情况下，序列图像压缩比可达到１４６．２．
The application of multiwavelet to the image sequence coding is studied. Through the use of little change in the data of two neighboring frames, repeat row pre filter method is improved and high speed in decomposition and reconstruction is obtained. After approximate quantitization and coding, the compression ratio of moving pictures is 146.2 in the case of good subjective picture quality.
