For thinning to work, your input image must look like this: before

This image was obtained by feeding raw input to Gabor filter (if I remember correctly). Code for Gabor filter is included in the repo, but I think it's buggy - that's why I didn't describe it in README.

Hope this helps.

Yeah, the code for Gabor filter will lose some data on the picture, how to fix or reduce it.

I haven't touched this code for years, I even forgot how it actually works (or not works, as should I say) :) Bottom line is, that I'm not planning to fix it anytime soon.

You may try to fix the bug if you want to, I'll be happy to merge your pull request :)

Hello, I try to use the gabor.py for the ppf1.png but the output is not same to you? I think the problem is the input block_size. And I don't know how can I calculate the input block_size. Can you please help me? Thank you.
