Hello,

I have developed an efficient Python implementation of the algorithm used by MATLAB's bwmorph('thin', ...). I believe this differs from the skeletonization algorithm provided by skimage and could be useful for people porting MATLAB code.

https://gist.github.com/joefutrelle/562f25bbcf20691217b8

is this of interest? If so I could take the time to bring the coding style up to PEP8 and make a proper PR out of it.
