A coding scheme is proposed to eliminate the redundancy of output vectors in pyramidal lattice vector quantization ( plvq ) . a fast algorithm of labeling lattice points and a fast algorithm of finding lattice points are presented . and the transmission priority in case of asynchronous transfer mode is suggested 提出了一种与图象本身无关的熵编码方法去消除金字塔格型矢量量化( plvq )的输出冗余：同时也提出了由格点输出索引和由索引输出格点的快速算法；而且还根据异步传输模式( atm )的特点，选择了传输的优先级。
