| Abstract: | A new method to find singular points from a fingerprint image based on spectral analysis is proposed in this paper. By utilizing the algorithm, we can extract the singular point within the process of fingerprint image enhancement, which can reduce the processing time. We also realize the algorithm on a TMS320DM642-based platform. Experimental resuits show the algorithm has good performance in embedded AFIS. |
