Why only image processing & enhancement code is available?
This module is the most important part of fingperprint recognition, like the most important part of license plate recognition is finding where the license plate is, it has greate impact on the final result (both correctness and performance). Besides there are a lot of excellent open paper about the remaining code (minutiae match), I think someone else must have better idea than me on the remaining part.
Why you don't update for such a long time?
I'm quite busy, so I need partners to co-work with me. A little lazy? OK, I admit that to some extent. But I also think that's one of the open source spirit, share & gain. right?
