Description: %% 本程序实现任意偶数大小图像第二代双正交97提升小波变换
%% 注1: 采用标准正交方法,对行列采用不同矩阵(和matlab里不同)
%% 注2: 为了保证正交,所有边界处理,全部采用循环处理
%% 注3: 正交性验证,将单位阵带入函数,输出仍是单位阵(matlab不具有此性质)
%% 注4: 此程序是矩阵实现,所以图像水平分量和垂直分量估计被交换位置
%% 注5: 此程序实现的是类小波(wavelet-like)变换,是介于小波包变换与小波变换之间的变换
%% 注6: 此程序每层变换相对原图像矩阵,产生的矩阵都是正交阵,这和小波包一致
%% 注7: 但小波变换每层产生的矩阵,是相对每个待分解子块的正交矩阵,而不是原图像的正交矩阵(%% of the program arbitrary size images even second generation biorthogonal wavelet transform 97
Note 1:% using standard orthogonal method, using different ranks of matrices (MATLAB and different)
Note 2:% in order to ensure orthogonality, all boundary processing, all with recycling
Note 3:% orthogonal validation, the identity matrix into the function, the output is still the unit matrix (matlab does not have the property)
% note 4: This program is a matrix to achieve, so the image horizontal and vertical components is estimated to be swapped)
