ANALOG VLSI MORPHOLOGICAL IMAGE-PROCESSING CIRCUIT

An analogue VLSI circuit that performs morphological image processing operations on the focal plane is presented. The circuit has been fabri cated using a standard digital CMOS process. We exploit the parallelis m of morphological image processing operations by using the massively parallel architecture of analogue VLSI arrays, achieving both high-spe ed and low-power computation [1]. The analogue circuit presented compu tes the grey-scale morphological operation of dilation. This system al so allows for programmability of the structuring element used in the d ilation operation.
