击中与否单通道光学处理器用于人脸识别

根据击中击不中运算的定义提出基于光学单通道相关器的灰度腐蚀的概念，证明了图像对具有三个灰度级的结构核的腐蚀操作等价于击中击不中形态学操作；给出选择正确的结构核灰度级的条件；设计了只有一个图像和一个灰度结构核的单通道非相干光学相关器来并行一步取阈完成击中与否运算。最后给出该处理器用于人脸识别的实验结果。

Face Recognition by the Use of an Optical Parallel Single-channel Hit-miss Transform Processor

A new algorithm in which the defined hit miss transform is reformulated by a grayscale erosion of the image with a grayscale structural element of three levels is developed. A necessary condition is defined to choose the correct intermediate grayscale level in the structural element. Then a single channel incoherent optical correlator with only an image and a structural element is developed to execute the hit miss transform in parallel by one step thresholding. Experimental results for the face recognition are demonstrated.
