Hi! I'm having a hard time with this. I need to evaluate each pixel on a image using a 7x7 window, where the pixel to be evaluated on the image will be located at the center of the window. How can I set up the code to move the window around the image and how can I specify conditions where I'm evaluating pixels on the boundary of the image, like a pixel located at (1,1) or at (512,768)? Any help will be greatly appreciated. Thanks!

You likely want to use the imfilter function exactly as in this example, but swapping out the 5-by-5 example filter with a 7-by-7 of your choice.
If you look at the options available for imfilter ( see documentation ), you'll see there's a couple things you can configure for boundaries.
