| Abstract: | The paper introduces an automatic recognition system of driving vehicle license number plate. From the front image of the vehicle we locate the place of the license plate by using multi-layer segment algorithm and separate the license plate from the background. Then we code the single English character and Arabic numbers by a shadow mask, pick up their characters, furthermore, recognize them by neural network. The whole algorithm is easy and the correct ratio of recognition is about ninety-six percent. |
