1. A traffic sign recognizing method, comprising: detecting a traffic sign candidate region from an input image using a modified census transform (MCT) feature; verifying whether the candidate region corresponds to a traffic sign using the MCT feature histogram for the candidate region; classifying a region of interest into the corresponding traffic sign using the MCT feature histogram for the verified candidate region; and matching the region of interest using a radial symmetry detection (RSD) based on voting in a gradient direction using a deviation of an X axis value and a deviation of a Y axis value of each pixel of the input image.
