Eric24	Posted - Aug 24 2011 : 19:32:35 I'm hoping someone here with some experience doing this can point me in the right direction. What I have is a color scan of a handwritten document. The background is mostly "solid", but not "white" or any other single color, but rather shades of white/gray (think old paper). The handwriting is mostly written with blue or black ink, occasionally some other color. My objective is to extract the handwriting from the background. So far, I'm thinking that some combination of "background color removal" and/or edge detection might do the trick. Is there some other approach I should consider? Any advice would be greatly appreciated! Thank you!

For example: ImageEnView1.Proc.ConvertToBWLocalThreshold(8, ietMeanMinMax, 6); You may need to change parameters depending by the background. Also, it may be necessary to remove isolated pixels with: ImageEnView1.Proc.RemoveIsolatedPixels(0); This is the result applying ConvertToBWLocalThreshold and RemoveIsolatedPixels to your image:
