| Abstract: | In this paper,the identification /authentication,the image procession,the fingerprint feature abstraction algorithm and implementation are studied,and the experiment study is done to this algorithm.The result indicates that the algorithm not only has good discrimination concerning the better-qualitied pictures but also has good identification effect on the poor-qualitied pictures. |
