Description: Fingerprint image preprocessing and feature extraction fingerprint identification is a prerequisite. Proposed a filter based on direction and the method of fuzzy fingerprint image preprocessing algorithm, and gives the fingerprint feature extraction and post-processing algorithms. First find the fingerprint image preprocessing fingerprint orientation field, and then filtered orientation field, and finally fuzzy binary images obtained. Fingerprint feature extraction is to start to get detailed fingerprint feature points and feature points based on pseudo-angle characteristics of the ridge line and remove the false feature points.
