随着信息技术的进步，对基于生物特征的准确个人识别系统的需求正在增加对这种类型的安全技术的需求，而不是使用ID卡或PIN号码的传统系统。在其他特征中，面部是最熟悉的元素，并且较少受到心理阻力的影响。作为一个简单而紧凑的识别系统，满足所需的性能，我们实现了一个混合系统的基础上的光学识别原理，使用多级波带片作为傅里叶变换透镜，我们报告的初步结果，其应用于人脸识别。本文介绍了第二代紧凑型并行相关器（COPaC II）的改进型设计和制作过程。COPaC II的尺寸为20 × 24 × 43 cm ~ 3，重量为6 kg。结果，我们获得了0%的错误率作为错误匹配率和0.3%的错误不匹配率，因此COPaC II重要识别安全级别足够稳定。为了进一步提高系统的处理量和稳健性，我们进行了性能测试，测试系统分别用作电脑登入装置和罪案调查的预检装置。在这两个实验中，一个高的成功识别率，如90%的识别率和94%的拒绝登录，获得。实验中还包括双胞胎检查伪装识别，并在亮度变化和任意大小的图像，以测试其鲁棒性的影响。
With the progress of information technology, the need for an accurate personal identification system based on biological characteristics is increasing the demand for this type of security technology instead of conventional systems using ID cards or pin numbers. Among other features, the face is the most familiar element and is less subject to psychological resistance. As a simple and compact recognition system satisfying the required performance, we implemented a hybrid system based on the optical recognition principle using a multi-level zone plate as a Fourier-transform lens and we report the preliminary results of their application to face recognition. In this paper, we present the design procedure and fabrication process for an improved version of a second-generation compact parallel correlator (named COPaC II), the size of which is 20 × 24 × 43 cm3 and weight 6 kg. As a result, we obtained a low error rate of 0% as the false match rate and 0.3% as the false non-match rate, thus the COPaC II significant identification security level is sufficiently stable. With the aim of further enhancing the throughput and robustness, we conducted performance tests where the system is used as a computer log-in device and as a pre-screening device for crime investigation. In both experiments, a high rate of successful recognition, such as 90% recognition and 94% rejection rate for log-in, was obtained. Experiments on twins to check the disguise recognition, and on the effects of changes in brightness and arbitrary size of images to test its robustness are also included.
