An improvement of real time car license plate detection in the surveillance system

We improve RTCLPD (Real Time Car License Plate Detection) method for detecting more than one car license plate in an image. The moving object detection method is applied to recognize the number of cars in the image. We used a simple condition to filter out the moving object which is not a car. Some parameters are estimated by the obtained moving object and RTCLPD is applied in the partial area of each moving object. Since RTCLPD is applied in each moving object, it can be improved to detect more than one plate in an image. According to the results, we detect the car license plate accurately in a short time and all plates are detected in an image.
