To improve traffic safety, an automatic traffic sign detection system would be important to assist the driver. In this paper, an approach for detecting Norwegian speed limit signs is proposed. It consists of three major steps: Color-based filtering, locating sign(s) in an image and detection ofnumbers on the sign. About 91% correct recognition is achieved for a selection of 198 images. Ongoing work is focused on video input analysis. For the covering abstract see ITRD E134653.
