Traffic Sign Detection Based on Color and Boundary Feature

This paper mainly presents an off-line traffic sign detection approach.Because their color and shapes feature are very different from natural environments,the algorithm described in this paper takes advantage of these features.It has two main parts.The first one uses the feature of red boundary and white region to segment the image,and then fuse their segmentation image.The second one uses Canny operator to analysis the boundary shape and locate the traffic signs.Some results from natural scenes are shown.
