Determine angle of rotation by finding squares. Then call imrotate().

Threshold to find dark regions, use regionprops, filter on size and perimeter^2/(4*pi*area) to detect squares of the right size. Then think a little bit about how to find angles. There are probably several ways, like maybe hough() or houghlines()???? Or use area of square and area of bounding box. Or use the corner() function. Try some. Experiment and have fun. Shouldn't be too hard.
