Car License Plate Location Based on Mathematical Morphology
The car license location is the foundation of the whole car plate recognition system, whose efficiency will directly affect the veracity of license recognition.
In this paper, the car license location is adopted on the base of mathematical morphology. Turn the inputted color car license image into gray image and detect the edge by using the Roberts operator. Eliminate the noise in the obtained binary image by using the erosion operation, and then the close operation of the mathematical morphology is used. Some connecting areas are formed. According to the area preparations and the marked connected regions, the license plate location are obtained. The results show that the method is simple, the location accuracy rate is higher, and it can meet certain real-time requirements.
