Core point detection is very important in fingerprint classification and matching process. We have developed a fast and reliable algorithm for core point detection based on orthogonal gradient magnitudes of orientation field of fingerprint image. It is found that the technique proposed herewith can improve the identification correctness with slightly better in computation performance.
