Patent

CA 2313803

A method and apparatus for the automatic extraction of linear features from digital imagery is disclosed herein. The proposed methodology derives from the Radon transform, yet has none of its basic disadvantages. Indeed, it is not limited solely to extracting straight lines, there are no false peaks or virtual maxima (peaks that do not represent the real line on the input image) in the transformed plane and the process does not have difficulty detecting line segments which are significantly shorter than image dimensions.
