摘　　要：提出一种广义互补编码方法，用于一步实现数学形态学击中击不中变换，并以非相干光相关器为光学实现硬件，利用液晶投影板作为实时空间光调制器，研制了一台光电混合目标识别处理器。实验结果表明识别率大于９０％，并对带有４０％噪声，５０％缺损和６°以内旋转的图像甚至不同表情的人脸图像均能识别。In this paper, an extensive complementary encoding method is presented for realizing morphological hit or miss transformation by only one step. An opto electronic hybrid target recognition processor is developed. An incoherent correlator is used as its optical implementation hardware and a liquid crystal display panel is used as its real time spatial light modulator. Experimental results have shown that the recognition accuracy is over 90%, and human face images with 40% noise, 50% loss, 6° rotation and even different facial expressions can also be recognized.
