| Abstract: | Detection of singularity of fingerprint images is very important.In this paper through analyzing some short-coming of the singularity detection method,a new approach for detecting singularity based on spectrum analysis of an orientation field binary map is proposed.The method is tested using fingerprint images and the recognition rate is90%. |
