The recognition system is able to both increase safety by compensating for a driver’s possible inattention and to decrease a driver’s tiredness by helping him follow traffic. An efficient algorithm for preprocessing digital images for the online detection of the road signs has been presented. It has been examined whether it is possible to use color space hue-saturation value for to select the red color. The algorithm for eliminating noises and increasing the accuracy and rate of detection has been developed. The obtained images are very suitable for the localization of road signs.
