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.
