They adopted different ways towards wavelet coefficient singly and could not make use of spatial partial individually features such as cross - scale fringe existed widely Davis在汲取了rinaldo和calvagno在分形块预测方案中，只是单一地对不同尺度系数用不同的处理方式的不足，提出了sqs编码算法。
Experiments show that the efficient motion estimation algorithm proposed can further reduce block matching distortion computations relative to conventional fast motion estimation algorithms with neglectable coding efficiency loss ( within 0 . 1db ) 提出一种基于节点模型的可变形块匹配运动估计算法来搜索最佳运动矢量。实验表明,在编码性能损失很小的条件下,可以使得运动搜索块匹配的运算量在通常快速运动搜索算法的基础上下降61 % 。
