Abstract

Hough transform is an effective method for the detection of the shape of object boundaries in image pattern analysis. Since the Hough transform is very computation intensive, it is essen-tial to parallelize the computation. However, an effective parallel algorithm is harder to obtain because it requires global informa-tion. In this paper we present an efficient parallel Hough transform algorithm for the detection of straight lines using mesh connected processor arrays. While other parallel algo-rithms take either 0(n2) or 0(n2) time, where n is the number of distinct values of a parameter and N is the number of edge pixels, our algorithm takes 0(n) time.
