Road Segmentation using Automatic Marked Watershed

Abstract

This paper proposes a road segmentation algorithm using a watershed. The proposed algorithm is a segmentation algorithm using an automatic marked watershed that automatically creates a road marker and a background marker using information about vehicles and lanes on road and it can solve problems of a watershed-based segmentation such as overmany regions or handworks for markers. The road marker has property for pure road areas in which lanes are included but vehicles are excluded and the background marker has property for the areas left in which vehicles and background are included. Results of segmentation applied to real road images show that the proposed algorithm can automatically creates appropriate markers and it can properly segments the required road area that include the lane with a vehicle and its both side lanes in various environments, and it is equal to the conventional algorithm using markers created by handwork in performance. 키워드 : 차도, 영역 분할, 자동, 마커, watershed Key word : road, segmentation, automatic, marker, watershed Received 22 September 2016, Revised 27 September 2016, Accepted 01 October 2016 * Corresponding Author Jeong-su Oh(E-mail:ojs@pknu.ac.kr, Tel:+82-51-629-6414) Department of Display Engineering, Pukoyng National University, Pusan 48508, Korea Open Access http://doi.org/10.6109/jkiice.2017.21.2.409 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
