I have an image with a colorized blob that has fuzzy edges (on top), and I want to create an outline for it made of straight lines (bottom): http://i.imgur.com/cJq0uui.jpg. I don't really need to fill it, just adding outlines will do. Can be turned into a black & white image. Can anyone point me to a simple transformation / procedure that can do it? Preferably something can I could easily find a code example for. Thank you

What, precisely, do you mean by "outline"? You will need to be able to state that clearly before you can do this.
