The Research And Application Of Method Of Digital Recognition With Noise

The technique of digital recognition with noise synthesizes the technique of computer vision and mode identify .It is an important part of intelligent controls system and has extensive application fields and the fine applied foreground. This article takes a vehicle license plate recognition system for example to dissect and carries on comparison of the existing methods or design for the main steps of digital recognition with noise: positioning ,prepare processing, incise and character identify.It mainly studies the steps and methods of realization of the system of the direct method, the BP network method and the Support Vector Machine method (SVM) and gets a higher identifying rate and reliability. And the SVM method takes special advantages if the solution of many problems such as the small sample, nonlinear, etc..After the completion of the main steps, a whole vehicle license plate recognition system is built. And it obtained better result.
