Multilevel 2-D Wavelet Decomposition Example code | Multilevel Matlab 2-D Wavelet examples

In below example to support for multilevel 2-D wavelet decomposition on Matlab.below syntax used to create your Multilevel 2-D Wavelet.

In matlab wavedec2 use this function for multilevel 2d- wavelet example as below.

>>N = 3; % 3-level 2d wavelet....

>>X = imread('input.jpg');

>>imshow(X);

>> [C,S] = wavedec2(X,N,'haar'); % we choosing haar wavelet.. C is band ,S is coefficients of bands

C is band value .Change bands values

In below we applying inverse multilevel 2d wavelet....

>>output = waverec2(C,S,'haar');

>>imshow(output);
