Any ideas how to detect, and therefore remove (approximately) rectangular borders or frames around images? Due to shading effects etc, the borders may not be of uniform colour, and may include or be partially interrupted by text (see examples below)? I've tried and failed on some of the examples below when thresholding on intensity and looking at contours, or trying to detect edges using the Canny detector. I also can't guarantee that all the images I do this on will actually have borders.
