Extraction of Vehicle License Plate Through Extended Hough Transform

Ever growing vehicle population has been a global phenomenon and thus the license plate recognition becomes an important task both from legal as well as database perspective. In this paper a method for extraction of license plate of a vehicle is presented using extended Hough transform (EHT). The extended Hough transform is used to efficiently extract the license plate of a vehicle, so as to later use it for identifying the vehicle through its license plate. This method has advantage over other methods that it reduces the need for large memory and has higher speed for processing. So it can be used for real-time applications.
