AUTOMATIC EXTRACTION OF LINEAR FEATURES FROM DIGITAL IMAGERY

摘要

A method and apparatus for the automatic extraction oflinear features from digital imagery is disclosed herein. The proposedmethodology derives from the Radon transform, yet has none of its basicdisadvantages. Indeed, it is not limited solely to extracting straight lines,there are no false peaks or virtual maxima (peaks that do not representthe real line on the input image) in the transformed plane and the processdoes not have difficulty detecting line segments which are significantlyshorter than image dimensions.
