摘要：
Automatic extraction of contextual information on road sign can be used in various applications such as scene interpretation and autonomous navigation. This paper proposes a method for the automatic detection of contextual information on Korean road sign. It usually consists of various information such as directional symbol, the name of place according to direction, and corresponding route number. All this information is automatically detected using image processing. First, target area containing a road sign on image is found using learning based object detection algorithm.. Next, grouping into Korean and English characters, direction symbol, and road's digit is done. Finally, contextual information is obtained by analyzing each group using color and geometric features.
