In this paper, a new technology based on the genetic algorithm and new image filter for recognizing road traffic sign from motion image captured by a CCD camera in a car was developed. In order to realize a real-time position recognition, the step genetic algorithm with search region limits and image filter (denoted by SVF) were proposed. The genetic algorithm with search region limits was employed to detect the position and size of traffic signs in real-time as well as SVF was employed to extract specified colors. The feasibility and validity of the proposed scheme are demonstrated through road driving experiments.
