1. fast processing
2. It can give you multiple regions in image if more than one number plate present
3. It can handle image rotation up to a certain degree( +- 35 ) .I used Eigen vectors.
4. No third party libraries like openCV or aforge ( yes some times i like to reinvent the wheels again )
See the video to see the project in action.
Although the number plate extraction parts works pretty good , I don't have a good OCR module. So i am having troubles to extract numbers from image. I tried using a simple back propagation neural network, its quality of recognition is not that great.Now i am trying to develop a rotation,scale invariant recognizer. It may take another 9 or eight months to do that. But if it works i think that would be a great achievement. I will try to post more updates here..
If you know any good optical character recognition library, please let me know.
