3-9 Recognition of a Pair of Road Lines Using a Ladder Type Active Contour Model

Abstract

We previously proposed a ladder type active contour model which detects individual road lines of constant width. Though the model is robust to noise in an image, it often fails in the recognition of a road line when a part of the line is hidden by the preceding vehicles. This paper describes a new method which enables the recognition even in such a case by combining two ladder type models corresponding to a pair of road lines.
