%% Filter Integral Image % %% % Read image into the workspace. % Copyright 2015 The MathWorks, Inc. A = imread('cameraman.tif'); %% % Pad the image by the radius of the filter neighborhood. This example uses % an 11-by-11 filter. filterSize = [11 11]; padSize = (filterSize-1)/2; Apad = padarray(A, padSize, 'replicate','both'); %% % Compute the integral image of the padded input image. intA = integralImage(Apad); %% % Filter the integral image. B = integralBoxFilter(intA, filterSize); %% % Display original image and filtered image. figure imshow(A) title('Original Image') figure imshow(B,[]) title('Filtered Image')
