Is there any program or method which can convert bit-map image into OpenVG path?

I've seen that a tiger image is used in so many application example and the image consists of over 300 paths and most paths have over 10,000 edge.

I cannot believe all those are made by a human....

So, I think there is a specific application which convert bitmap image into OpenVG path.. right?~~

If so, please somebody give hits or the application to me at
