Java implementation of skeleton algorithm extraction based on index refinement

Recent research Verification Code recognition, also looked at some image recognition data, one of the font refinement to extract skeleton of the algorithm on-line without Java version of the implementation, so chose a Python implementation version of the Java code rewrite.

The Python version implements the address:

Because I do not understand the Python grammar, but also go directly to the view of the language of the tutorial, for this also fell into a pit. See:

Http://www.cnblogs.com/chyu/p/4335950.html

Because I am not very good at image processing here, Python is also a temporary look, so this refinement of the skeleton extraction algorithm is the direct migration of the original code, and did not do anything optimization, and so on. The code is rough.
