The Project is to investigate the current techniques for fingerprint recognition. This target can be mainly decomposed into image preprocessing, feature extraction and feature match. For each sub-task, some classical and up-to-date methods in literatures are anal yzed. Based on the analysis, an integrated solution for fingerprint recognition is developed for demonstration. The program is coded in C Language. For the program, some optimization at coding level and algorithm level are proposed to improve the performance of fingerprint recognition system. These performance enhancements are shown by experiments conducted upon a variety of fingerprint images. Also, the experiments illustrate the key issues of fingerprint recognition that are consistent with what the available literatures say.
