Paper Abstract

A novel scheme for implementing gray scale image hit-or-miss transform (HMT) in one optical step with only one optical correlator is presented. This scheme uses area- complementary-encoding to represent each pixel of gray scale images. Using an incoherent optical correlator to optically perform correlation and a microcomputer to perform nonlinear thresholding electrically, the area-complementary-encoding gray scale image HMT is realized for auto target recognition.
