regarding the background part, I tried this successfully myself, albeit with a strictly white background. In your case, I would copy the image and paint over the face in a bitmap editor like Gimp etc. in order to remove the face completely and have just the background on a separate image. You can then proceed as follows (this is a shell script for Linux, but you can modify this easily for any other OS): ---- #!/bin/sh convert image_with_face.extension -fuzz 25% -background.extension \ -compose change-mask -composite final_image.extension display final_image.extension ---- The last line is optional, of course. You may have to try out different valuers for '-fuzz'. Here's an example from my blog (the text is in German, but I guess the image speaks for itself): http://grafomatic01.twoday.net/stories/4839779/ I found this to work really smoothly, and as you can see, the final image doesn't contain any color "spill" at the edges of the object.
