%% Haar Transform of Image Down to a Specified Level % Show the effect of limiting the maximum level of the 2-D Haar transform % on an image. %% % Load and display the image of a cameraman. im = imread('cameraman.tif'); imagesc(im) %% % Obtain the 2-D Haar transform to level 2 and view the level 2 approximation. [a2,h2,v2,d2] = haart2(im,2); imagesc(a2)
