Algorithms

Preprocessing:

    Before doing minutiae and verification processes, we have to do image enhancement, which includes histogram equalization, FFT filter, bilinear enlargement, and binarization.

Minutiae Extraction:

   After finishing preprocessing step, we could extract minutiae from our fingerprint images, which includes ridge tracing and fake minutiae removal.

Verification:

    Finally, we have our database of processed fingerprint images and test fingerprint images to do the verification.
