| Benefit from the lower cost and the easier installation, Intelligent Traffic system (ITS) based on high definition (HD) picture is increasingly used. In this paper, we describe a edge and color feature based method, which is able to locate and extract license plate from the high definition images in real-time. In the proposed algorithm, the edge feature is fully utilized to find the candidate region of the license plate (LP). And then, a edge identity similarity method is employed to adjust the position of each candidate, which can get the accurate LP position. Finally, an effective evaluation method is proposed to get the real LP from the candidate region. This thoroughly integrated system can obtain accurate localization of LP real-time in the HD traffic pictures under complicated background and changing illumination conditions. The experiment results indicate that the presented system is excellent in accuracy with a good speed. |
