EDContours: High-Speed Parameter-Free Contour Detector Using EDPF

Abstract

We present a high-speed contour detector, which we name EDContours, that works by running our real-time parameter-free edge segment detector, Edge Drawing Parameter Free (EDPF), at different scale-space representations of an image. Combining the edge segments detected by EDPF at different scales, EDContours generates a soft contour map for a given image. EDContours works on gray-scale images, is parameter-free, runs very fast, and results in an F-measure score of 0.62 on the Berkeley Segmentation Dataset (BSDS300).
