So I'm trying to use mean filtering to process an image. The idea of mean filtering is simply to replace each pixel value in an image with the mean (average) value of its neighbors, including itself.

It doesn't come out the same. You either aren't looking at it magnified enough. Or, for tiny displayed images, you'll need to increase the blur window to notice a difference. This code works:
rgbImage = imread('peppers.png');rgbImage = im2double(rgbImage);windowSize = 15;avg3 = ones(windowSize) / windowSize^2;subplot(2,1,1);imshow(rgbImage)blurredImage = imfilter(rgbImage, avg3, 'conv');subplot(2,1,2);imshow(blurredImage)
