摘要
根据Joint变换相关识别原理进行指纹识别,讨论了以Machzehnder干涉仪作为输入部件的光学系统的特点,详细分析了检测过程中噪声的来源和机制,并给出文字、清晰指纹、模拟现场指纹和真实现场指纹的实验结果.
The joint transformation image correlation is used for fingerprint pattern recognition.An optical system with a Mach-Zehnder interferometry as its input device is described.The noise mechanisms during detection are discussed in detail.The experiment results for characters, distinct fingerprints, simulative field fingerprints and real field fingerprints are presented.
