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.
If you know any good optical character recognition library, please let me know.
