Paper Abstract

The fingerprint (FP) provides an optimal foundation for Automatic Personal Identification Systems. In this paper, A new method of fingerprint collection that based on the improvability of images quality is proposed. The approach is mainly to enhance the accuracy of Automatic Fingerprint Identification Systems (AFIS) by indirect-contact collection. In a preliminary stage, The capture of fingerprint images is tested with an available contact approaches. Similarly captured clear images by using semiconductor capacitive sensor. And then, The integrited nondistortion fingerprint is indirect-contact collected by using a super-hemisphere-immerge lens and CCD camera with laser or incoherent light. It compares both of two collect methods on the basis of the experiments. The methods of fingerprint optical correlate identification and pattern recognition are discussed. The methods simply achieves on system.
