%% Inverse 2-D Haar Transform of an Image % Obtain the inverse 2-D Haar transform of image and view the % reconstructed image. %% % Load the image and obtain its 2-D Haar transform. im = imread('mandrill.png'); [a,h,v,d] = haart2(im); %% % Use the inverse 2-D Haar transform to reconstruct the image. xrec = ihaart2(a,h,v,d); %% % Compare the original and reconstructed images. imagesc(im) title('Original RGB Image') figure imagesc(uint8(xrec)) title('Reconstructed RGB Image')
