چکیده

The paper describes a detection method of car number plates on digital images. The method inputs the graytone image of a car and extracts from it the characters on the number plate. The proposed method makes use of the morphological operators: morphological reconstruction, filters based on it and top-hat operators. The method can be applied to access control systems supervising the car traffic in the restricted areas. Streszczenie.

A Robust Automated Process for Vehicle Number Plate Recognition

A moving/parked car embeds mainly speed and momentum, and is surrounded by its environment. Both the cases are extremely unpredictable so, dynamically both the situations are handled. Any image captured is processed with edge detecting algorithm to recognize the number plate and simultaneously solve the problem of redundancy and speed issues in processing the image keeping visual quality. Keywo...
