Paper Abstract

Hardware has been designed for high speed acquisition of the boundaries of objects in binary images. The boundaries, described using chain codes, are encoded from line scanned images and only one line of image data is stored at one time. High speed (5-10MHz.) and low memory requirements enable the hardware to process large images (2048 pixels wide) required for some applications of image processing to automatic inspection e.g. the inspection of bare printed circuit boards (PCB's). The operating principles of the hardware have been validated in a software simulation which itself is a useful image processing tool.
