摘要
基于运动补偿的编码算法在运动图象压缩中得到非常广泛的研究和应用。该文提出一种基于数学形态学形态变换的运动补偿编码方法，通过形态变换确定对宏块中的不规则小块是否进行分割，以运动矢量比特数的增加换取帧间位移误差场（DFD）能量的大大降低，从而达到了提高压缩比（或相同压缩比下提高图象质量）的目的。
： Methods based on motion compensation have been widely researched and used in image sequences coding．This paper presents a method of motion compensation based on morphological transform．It determines small blocks which have different motion vectors to the marco block which it belongs．The sizes and motion vectors of these small blocks are calculated and coded in algorithm．The number of bits used in coding these data can be compensated by the number of bits of DFD which is more．It gets better results compared with MPEG－I when used in some examples．
