Paper Abstract

A hybrid optoelectronic morphological processor built in the shadow casting architecture is presented. The processor is programmable in both input planes. Binary slices of an input grey scale image and a structuring element of arbitrary size and shape are introduced into the processor by means of Epson liquid crystal spatial light modulators composed of 320 by 264 pixels. We present the quality of optoelectronically made morphological operations in comparison with digital results. The degree of conformity of the results obtained with both methods is measured in terms of the mean (per pixel) absolute error. An analysis of accuracy of the hybrid processor is presented. Several sources of errors, such as for example diffraction effects are discussed.
