Abstract

The Hough transform (HT) detects lines in an input but not their location. We describe a new way to determine the position of a line from HT data. The line position information is extracted from the shape of the HT pattern around the HT peak. Results are shown illustrating this algorithm on single- and multiple-line input images.
