NOVEL GRAY IMAGE-PROCESSING IN A SINGLE OPERATION OPTICAL MORPHOLOGICAL PROCESSOR

A novel optical morphological processing technique with only one opera tion for gray images is proposed and an incoherent gray image real-tim e processor is constructed. In this processor the morphological proces sing of gray images and gray structure elements is simplified into two convolution thresholds (one between a gray image and a binary structu re element, and another between a binary image and a gray structure el ement) and one algebra operation. It can reduce the number of operatio ns and increase the processing speed greatly. Some applications of opt ical morphological gray image processing have been studied.
