I tried using imcrop to select a rectangular region of interest but for some reason it didn't work when I used another image (different size). I tried using the roipoly function to select the region of interest and that worked every time. However, I need to restrict it to a rectangular region of interest. Is there any way I can do this using 'roipoly'?
