摘要
指纹识别具有很好的方便性和可靠性,是现代社会应用最广的生物特征识别技术.本文介绍指纹识别技术的发展和分类,论述了基于联合变换相关器的光电混合指纹识别技术,包括指纹取像技术与指纹预处理、指纹图像的匹配、系统的性能参数的定义以及光学联合变换相关器的各种改进方法,讨论了光电混合指纹识别技术的发展方向.
As one of the biometrics techniques, fingerprint recognition had been widely used for its convenience and reliability. An overview of the develoment and classification of fingerprint recognition technique was described. The technique of opto-electronic hybrid fingerprint recognition system based on joint transform correlator was discussed, including the capture of fingerprint image, image pre-processing, image matching with joint transform correlator, definitions of system’s performance parameters and the improvement of joint transform correlator. In the end, the developing direction of the technique of opto-electronic hybrid fingerprint recognition system was discussed.
