EDLines: A real-time line segment detector with a false detection control

A linear time line segment detector that gives accurate results, requires no parameter tuning, and runs up to 11 times faster than the fastest known line segment detectors in the literature; hence the name EDLines.

Abstract

We propose a linear time line segment detector that gives accurate results, requires no parameter tuning, and runs up to 11 times faster than the fastest known line segment detector in the literature; namely, the line segment detector (LSD) by Grompone von Gioi et al. The proposed algorithm makes use of the clean, contiguous (connected) chain of edge pixels produced by our novel edge detector, the Edge Drawing (ED) algorithm; hence the name EDLines. The detector includes a line validation step due to the Helmholtz principle, which lets it control the number of false detections. With its accurate results and blazing speed, EDLines will be very suitable for the next generation real-time computer vision and image processing applications.
