106 A Robust Method for Universal License Plate Detection of Vehicles

Vehicle License Plate Detection plays a pivotal role in Vehicle License Plate Recognition for commercial as well as private vehicle for intelligent transportation system. This paper presents a robust method for Vehicle License Plate Detection in various cases. Here an algorithm is devised to detect Vehicle License Plate region using RGB (Red Green Blue) filtering, Optical Character Recognition (OCR) and Geometrical features of Vehicle License Plate. This method uses color information to approximate the region of License Plate and then utilizes OCR to eliminate undesired region. Finally geometrical features of License Plate are used to extract the actual License Plate. Experimental results indicate that the proposed method is robust, accurate and works well in various environmental conditions.
