Abstract

Fingerprint recognition is implemented on Ti DSP chip Ti 5402. The algorithm is prompt and practicable. Enhance part adopts a fast orientation filter to improve inputting image quality combining fast orientation interpolation method. On the other hand, the orientation field is used in fingerprint image segment. Matching part uses point match method and combines some post-processing in order to get good match result. One fusion way is introduced in enrollment. In DSP implement phase, the system frame adopts one kind of dispatched system structure aiming at the 5402 features. Otherwise the algorithm of fingerprint recognition is modified and optimized based on DSP instructions. Experiment result indicates that system performance is good.
