Re: Finger Print Identifier
kaushi,
Sorry for the late reply. I havn't read the code you sent, as I have no Matlab in my office PC. For the ridge ending, I think you can refer to kiki's code. The code works well to detect the ridge ending and bifurcation.
For thinning, you can use morphological thinning instead of canny. FYI, canny is a edge detection method. Once you see a satisfactory result of thinning, then should be no problem.
Singular point detection is not minutiae...Minutiae is the ridge bifurcation and ending. In fingerprint image, there's a core point. The core point is the singular point. You can read some books if you want to know more about singular points. Delta is another type of singular points.
After you extract the features, then you can match them using Jain's method and WFMT. It's good that you can compare the result of both methods.
Wish you all the best.
