Non photorealistic rendering (NPR) - Cartoon rendering

I wrote some software based on some academic papers to render a photograph with a cartoon effect (abstracted image, thick lines, and cel shading). The software takes a photograph and turns it into a toon (cel shading, toon shading). Turn photo into cartoon. Check http://3dstereophoto.blogspot.com/p/p... for free image-based non photorealistic rendering software for windows 64 bit.
