Abstract:
This paper studied the detection algorithms of indicative traffic signs. First, the color segmentation was recorded along with a fast HSV color search method, and later the morphologic preprocessing was taken on the binary image after the color segmentation. Second, circularity and corner detection combined with geometric characteristics were used to judge if a region was an indicative sign. Last, in view of the incomplete edge of the round sign after the color segmentation, a new algorithm was raised based on a distance histogram for confirmation. Experimental results show that this algorithm is accurate and robust for detecting indicative traffic signs in real traffic environments, and also meets the realtime demand. 
