OPTICAL 3-DIMENSIONAL STACKED MORPHOLOGICAL PROCESSOR MODULE WITH VARIABLE THRESHOLDING

A compact stacked integrated module of optical mathematical morphologi cal processor is developed, which consists of a weighted interconnecto r of the building blocks like calcite and quartz plates and a variable thresholding device. Based on the Boolean decomposition for morpholog ical function and the thresholding for weighted convolution, a simple algorithm with only the programming of threshold levels is developed. Thus, any morphological image professing function can be performed by using a series of different threshold levels.
