Tire marks printed correctly can ensure the tire used properly. Tire mark regions in a tire image being extracted correctly are the first guarantee in a tire mark recognition system. In this paper, extraction algorithm based on radial scan method is discussed. Experiment results show that half character be extracted to tire mark regions occasionally via radial scan method. Hence, an improved extraction algorithm named sector-scan method is given to solve the problem. Experiment and analysis are also given in the end of the paper.
