The main object of this research is performance enhancement of parallel optical facial recognition by the construction of the new database on 3-dimentional wire flame model and the distributed database, and realization of multiple optical storage. The main results throughout these two years' research since 1998 are presented below.1) Recognition rate improvement by the construction of the database based on 3-dimentional wire flame model :We constructed two kinds of new database using the wire flame model. The one is to make the average face from one's several facial expressions and the other is to create some multiplex facial images, which contains five of each one. Choosing ten persons from the registered ones with some changes over time and the unregistered, we performed recognition experiments and concluded that these two database are conductive to recognition.2) Recognition speed improvement by construction of the distributed database :Categorization division by two kinds of facial … More index for the facial image retrieval was carried out from mass database. It was confirmed that the distribution to five groups was possible by two kinds of facial index. Reproducibility of 98% can be obtained for the images taken up 6 years ago and operation speed can be improved when the distributed database is used.3) Readout speed improvement by using the photo-refractive multiple optical memory :We sought to optimize these conditions with a view to applying SBN signal crystal to multi-channel multiplexed memory for reference image database of our facial recognition system and succeeded in recording 120 images.4) Application experiments to security system :The recognition of portraits, of which acquisition conditions very widely, is carried out. It was confirmed to have the robustness in which this system is excellent, on the assumption of the crime investigation. The result of the recognition experiments shows that the recognition rate exceeds 80% even after the portraits were taken a few years ago.5) Trial fabrication of compact parallel optical correlator :A compact prototype parallel optical correlator, whose size is 230×150×163 mmィイD13ィエD1, wad designed and devised. The experimental results of this compact system to facial recognition were evaluated with 100 person's database and proved to be successful. Less

本课题的主要研究内容是通过建立三维火焰模型数据库和分布式数据库，实现多路光存储，提高并行光学人脸识别的性能。从1998年开始，经过两年的研究，取得了以下主要成果：1）建立基于三维火焰模型的数据库，提高了火焰识别率：利用三维火焰模型建立了两种新的数据库。一个是从一个人的几个面部表情的平均脸，另一个是创建一些多重的面部图像，其中包含五个每一个。从已注册的、随时间发生变化的人脸和未注册的人脸中分别选取10个人进行识别实验，实验结果表明，这两种人脸数据库都有利于识别。2）通过构建分布式人脸数据库提高识别速度： ...更多信息 从海量数据库中进行人脸图像检索。通过两种面部指数的测定，证实了将其分为五组的可能性。对于6年前拍摄的图像，可以获得98%的再现率，并且当使用分布式数据库时，可以提高操作速度。3）通过使用光折射多重光学存储器提高读出速度：我们试图优化这些条件，以便将SBN信号晶体应用于我们的面部识别系统的参考图像数据库的多通道多重存储器，并且成功地记录了120幅图像。4）安全系统的应用实验：识别的肖像，其中收购条件非常广泛，进行。在犯罪调查的假设下，证实了该系统具有良好的鲁棒性。实验结果表明，即使在几年前拍摄的人像照片上，识别率也超过80%。5）小型并行光学相关器的试制：设计并制作了一台尺寸为230×150×163 mm的小型并行光学相关器样机。在100人的人脸识别数据库上进行了实验，结果表明该系统是成功的。少
