Abstract: This paper introduces how to de-noise automobile image and to locate license plate with wavelet on complex background, andexpatiates how to classify and recognise character of vehicle license plates with BP algorithm integrated with linear perceptron. Experiments showthat the design project is easy to be realized, has a good real-time performance, has a high recognition rate and can be the same with recognition ofvehicle license plates on complex background.
