子能和、求组大家了
To complete our discussion of the DWT,let's look at how the wavelet coefficient matrix is applied to the data vector.The matrix is applied in a hierarchical algorithm,sometimes called a pyramidal algorithm.The wavelet coefficients are arranged so that odd rows contain an ordering of wavelet coefficients that act as the smoothing filter,and the even rows contain an ordering of wavelet coefficient with different signs that act to bring out the data's detail.The matrix is first applied to the original,full-length vector.

作为我们对DWT的讨论的最后一部分,我们看一下怎样把小波系数矩阵运用于数据向量.小波首先运用于一个层次化的算法中,也叫做金字塔算法.小波系数的排列方式是奇数行包括按序排列的用于平滑滤波的小波系数,偶数行包括按序排列的、具有不同的正负号的、提取数据细节的小波系数.该矩阵首先运用于初始的完整长度的向量.
