FINGERPRINT PREPROCESSING ALGORITHM BASED ON DOUBLE COORDINATES
Considering the features of fingerprint, i.e. the local orientation, we employ a preprocessing algorithm based on double coordinates, not based on gray level distribution. This method, prepared with some single coordinate methods, is effective for both reducing orientation error and wiping out noise, and has better performance for preprocessing of noisy fingerprint images.
