The application of computer technology in the field of traffic greatly improves the efficiency of traffic management. Auto-detection image technology ,as the main source of information is being more and more attention. The rapid development in recent years, the computer for traffic management brings a great change, computer advanced processing techniques can not only freed people from manual observation and monitoring the cumbersome, but also can greatly improve the accuracy, the vehicle license plate automatic recognition system is developed in the background and purpose of such. Now, the license plate recognition is an important research topic, in the modern intelligent transportation systems, computer vision and pattern recognition technology is an important part of intelligent traffic management. In order to make the vehicle license plate recognition accuracy as high as possible, image preprocessing is very important, for image denoising is a very important step, in the image preprocessing. Wavelet analysis is a new branch of a mathematics in late twentieth Century began to rise, both in the field of signal processing, geological
