In order to effectively carry out the fingerprint image recognition, this study proposes a fingerprint preprocessing algorithm and feature extraction technology. In the fingerprint image preprocessing, this study gives the location method of region of interest. In terms of feature extraction, this study extracts the decomposition energy features of fingerprint. In terms of matching recognition, this study presents a new recognition method for fingerprint and uses the method to carry out the matching and recognition of fingerprint. In the simulation, the presented fingerprint recognition method is compared with several existing major fingerprinting methods. The comparison results show that the proposed recognition method is more accurate and faster than some existing better recognition methods. Its recognition precision is higher, the recognition speed is faster and the anti-noise ability is stronger. These researches in this study on fingerprinting promote an improving of the accuracy and speed of recognition and provide a new way of thinking for target recognition, which has an important theoretical references and practical significance.
