It can be done. Those little white squares make it possible. If I was hired to do that task, I would load the image into a picture control and search for the two white squares. The distance from the left edge of the left square to the left edge of the right square is your "n" for your n x n matrix. So, starting at the top, left edge of the right square, I would carve out n pixels down and n pixels right. Doing the same with the left square would give me two n x n matrices. I could then re-draw the picture control to place the two matched matrices side by side.
