%% 3-D Wavelet Transform Using Specified Decomposition and Reconstruction Filters % Specify the decomposition and reconstruction filters as a cell array. % Construct 8-by-8-by-8 matrix of integers 1 to 64 and make the data 3-D. M = magic(8); X = repmat(M,[1 1 8]); %% % Obtain the 3-D discrete wavelet transform down to level 2 using the % Daubechies extremal phase wavelet with two vanishing moments. Input the % decomposition and reconstruction filters as a cell array. Use the % periodic extension mode. [LoD,HiD,LoR,HiR] = wfilters('db2'); wd2 = wavedec3(X,2,{LoD,HiD,LoR,HiR},'mode','per');
