Paper Abstract

Road segmentation is the critical step in a vision system for outdoor road following. This paper presents a new method for color road segmentation. The basic idea of the method is as follows: each pixel of a color image consists of red, green, and blue intensity values; it can be considered as a feature vector in 3-D RGB space, and the road segmentation can be translated into a statistic classification problem. First, a color normalization transform is used to erase the shadows in a color image; then, the optimal discriminant plane technique is used for feature decorrelation; finally, road segmentation is completed by a minimum distance classifier designed on the optimal discriminant plane. We have done a lot of experiments, and the results show that the present method is effective.
