An optical processor for high speed human face recognition

设计了一种用于快速人脸识别的光学协处理器。提出正负图像组合编码方法，一步实现了通常需要三步的数学形态学击中击不中变换，提高了识别速度。改进传统的识别判据，改善了识别效果。采用一个液晶投影板同时显示待识别图像和参考图像，简化了结构。给出了实验结果。

An optical processor for high speed human face recognition is designed. An original complementary composite encoding method is presented, so that the morphological hit or miss transform, which usually needs three steps to achieve, can be done in only one step. Traditional identification method is modified to enhance the recognition performence. One liquid crystal display (LCD) panel is used as two real time SLMs for both testing image and training image so that the processor is more compact. The experimental results are given.
