How do I select a window of pixels around a pixel?

I need to select a window of 7 * 7 pixels around a selected pixel and navigate through each pixel in an image (grayscale binary image) using a for loop within the window and extract brightness intensity of each pixel wihin the window. I needed to find the mean of intensity value.

Valuable guidance and help will be highly appreciated

Thank you in advance
