Classification of Road Signs Using Color, Shape and Texture Feature Coefficients by SOM

Abstract

In this paper a new method to detect road signs from color road images and to discriminate them is proposed. This problem has been recognized as an important research field of ITS(Intelligent Transportation Systems). Proposed Self-Organizing Map is constructed by using three kinds of indices, feature of color rate, shape feature coefficient and texture feature coefficient. Experimental results show this method is sufficiently efficient for practical use.
