Abstract
An optoelectronic morphological processor for industrial on- line inspection is presented in this paper. The principle of the processor is based on the morphological hit-miss transform. By using an extensive complementary encoding method, which combines the foreground and background of an image into a whole, the hit-miss transform, which usually needs three steps to perform, can be implemented in only one step. The optical implementation hardware is based on an incoherent optical correlator due to its compactness in structure and immunity to coherent noise. The experimental results are given.
