摘　　要：运动图像在时间域上的数据相关性很大,利用相关性屏蔽无变化数据,使之表现为大量连续相同数据,进而用行程编码进行压缩。对帧间施行的基于异或运算的无损压缩算法和基于差值量化的有损压缩算法对远程教学及网络视频会议图像传输、监视系统的开发有重要实用价值。Moving images have great data relativity along time zone, which are used to shield unchanged data in order to get large same continuum data. Those data can be compressed on run- length encoding. Two algorithms acted between frames are put forward, that are loss - free canpress algorithm based on XOR and lossy compress algorithm based on differential quantum, which are benefit for distance education, network meeting and watching system.
