If anyone is looking for a challenge to implement in CUDA, try vectorizing bit map art.
I found this new technique on slashdot. Because the server hosting the original PDF paper was overloaded with traffic, someone mirrored the PDF research paper as images: Imgur: The magic of the Internet
I would really like to see this algorithm implemented in CUDA, possibly to upscale standard definition cartoons (Simpsons, etc) to HDTV resolution.
