Abstract

License plate location is the key to the recognition system of motor vehicle license. This paper presents an algorithm for license plate location based on compound mathematical morphology. An edge detection operator is designed for the edge extraction of the license plate image, with a clear edge image obtained. Then, the horizontal and vertical projections are used to locate the license plate area. The experimental result shows that the algorithm is accurate and efficient in the license plate location.
