有限长二维子波变换的算法结构

子带编码是图象信号压缩的一种有效方法。在子带编码系统中，利用子波变换的良好的时间（空间）和频率域局部化特性将图象信号分割成子带信号，可以改善压缩效率。从一维有限长子波变换的算法结构出发，利用矩阵Ｋｒｏｎｅｃｋｅｒ积的性质推导了一种用于图象压缩的二维有限长离散子波变换的算法结构。

The subband coding is an efficient method of image compression.In the subband coding system,the utilization of the local performances of the wavelet transform in both time (spatial) and frequency domains splits the image signal into subband signals,leading to the improvement of the compression efficiency.Starting from the algorithm structure of 1-D finite wavelet transform and relying on the properties of Kronecker product,this paper deduces an algorithm structure of 2-D finite wavelet transform suitable fo...
