Taking advantages of the special characteristics of traffic signs, TSR systems typically rely on the color and geometric information in the images to detect the ROIs. Hence, color segmentation is common to most TSR systems, so are edge detection [5] and corner detection techniques [6]. After identifying the ROIs, we extract features of the ROIs, and classify the ROIs using the extracted feature values. Researchers have explored several techniques for classifying the ideographs, including artificial neural networks (ANNs) [7], template matching [8], chain code [9], and matching pursuit methods [10]. Detection and recognition of traffic signs become very challenging in a noisy environment. Traffic signs may be physically rotated or damaged for different reasons.
