Adaptive Recognition Algorithm for Fingerprint Image Detail Feature in Embedded System

Fingerprint recognition based on Gabor filter algorithm research, the preprocessing of fingerprint images were collected to obtain effective area the size of the fingerprint, fingerprint image gray level information. Based on Gabor filter of equalization, normalization of fingerprint image segmentation, filtering and enhancement; After the process of enhancing the fingerprint feature extraction, classification and details matching, realize the precise identification of fingerprints in the embedded system. Fingerprint identification algorithm is put forward by the experimental results show that the recognition efficiency and higher identification accuracy, in the embedded system application effect is good.
