Proposed filtration algorithm for fingerprints images is based on iterative algorithm for image binarization which minimizes within class variance for image foreground and background classes. The proposed solution was modified to fit better to local structures of fingerprint pattern using Gabor filters and directional filtering. The algorithm was tested on fingerprint images database, with low quality images, giving very good results in reducing noise and disturbances.
