<p>The implementation of a Hough transform processor using a wafer-scale-integration technology, restructurable VLSI circuit is described. The Hough transform is typically used as a grouping operation in an image processing sequence. The transform discussed here groups pixels in order to extract linear features. This calculation is realized with a wafer-scale processor that allows a complete line extraction system to be integrated on a single PC board. Also discussed is the use of the CAD tools that allowed this processor to be realized without incurring silicon layout and processing overhead.</p>
