A novel method for detecting edges and lines simultane-ously and automatically is proposed. This method, based on phase congruency and tensor voting (hence PCTV), makes use of the properties of how edges and lines are built from the Fourier decomposition of an image, and how the primary vi-sual cortex responds to them, instead of making assumptions on the intensity profiles of the regions near a feature. Experi-ments showed that the detection results were more consistent to the “ground truth ” manually drawn by humans. For detect-ing edges, this method is superior to three commonly used detectors in that it reduces the production of false detections.
