说明：  针对小波变换和多级树集合分裂图像编码具有浮点数运算、算法复杂等特点,采用整数实现的提升格式代替了原来的小 波变换,并结合提升小波变换和DCT变换的特点,提出了一种改进方案。
(For wavelet transform and multi-level set to split the tree image coding with floating-point computation, algorithmic complexity, etc., realize the upgrading of the use of integer format instead of the original wavelet transform, combined with lifting wavelet transform and DCT transform, an improved program.)
