I have no idea honestly... One pointer that might be worth exploring, which is not quite L-Systems but might be related is Fractal Compression. I've read that there are algorithms to compress images into a "closest" IFS – iterated function system. https://en.wikipedia.org/wiki/Fractal_compression https://en.wikipedia.org/wiki/Fractal_compression Maybe one could come up with a way of going from an image via fractal compression to an IFS which could then be used as the basis for an L-system? Most of the L-Systems that are on this site are from Paul Bourke – http://paulbourke.net/fractals/lsys/ http://paulbourke.net/fractals/lsys/ Which is a really awesome resource!
