Abstract

This paper discusses a VLSI implementation of a fast contour tracing algorithm. Since Freeman published his chain code method for encoding the contour of binary images in 1961, this contour tracing method has been used in many different applications. In this paper, Freeman's chain code algorithm has been reformulated so that it can be implemented in array processing. A complete look-up table was first presented and we have derived from that an adaptive selection-inhibition circuit coupled with a priority encoder. From a VLSI implementation point of view, those circuits not only have area and speed advantages, but also are easy to lay out.
