I've been researching Sobel Filters for edge detection. I then use that information to identify bounding information so I can crop out borders programmatically. I also like OMGtechy's comment on converting to YCrCb or YUV and throwing out the Luma component. MSDN has an article on RGB to YUV Strangely enough, looks like it's HLSL (shader).
One possible approach is this: Convert to the YCrCb colour space and discard the Luma (Y) component. Compute a quality metric (see below), See if the quality metric is above a threshold (see below), Quality Metrics ASNR PSNR SSIM Threshold This will be largely trial and error; you'll just have to tweak it until you get the results you want. I'd ...
