摘要
给出一种单通道光学相关实现击中与否运算的算法和光学装置。此法基于形态学中腐蚀运算和光学相关的关系及阈值操作，在非相干光学相关器中，将前景结构核元素编码为１，背景结构核元素编码为α（α满足一定条件），只需用原图像与前景和背景结构核进行相关，然后对相关结果取阈值为Ｋ（前景结构核元素的像素数），即可得到击中与否运算。
A simple algorithm of morphological hit miss transform by single channel correlation in an incoherent optical correlator is proposed, which is based on Boolean decomposition for morphological function and thresholding operation for correlation. In reported optical hit miss processor, an original input image correlates with both foreground and background structuring element pair. By properly coding the foreground and background structuring element pair, and then thresholding at the number of foreground SE level, the single channel correlation for hit miss transform can be realised. Thus, The hit miss transform can be realised optically in one parallel step. Any morphological image processing functions can be implemented by repeated use of the optical processor with different structuring elements. Experimental results are given.
