### Abstract

: We present an analogue VLSI circuit that performs morphological image processing operations on the focal plane. The circuit has been fabricated using a standard digital CMOS process. We exploit the parallelism of morphological image processing operations by using the massively parallel architecture of analogue VLSI arrays, achieving both high-speed and low-power computation [1]. The analogue circuit presented computes the grey-scale morphological operation of dilation. This system also allows for programmability of the structuring element used in the dilation operation. Introduction Mathematical morphology is a nonlinear image processing approach that uses set theory to perform functions such as object detection and image segmentation [2][3]. We have developed analogue VLSI circuits that perform the primary operations of morphological image processing [4][5]. These circuits exploit the parallelism of morphological image processing operations by using 2-dimensional arrays of smart p...
