A Kind of Car License Plate Location Based on Color Feature and Mathematical Morphology

Abstract:

The proposed method of the license plate location is based on mathematical morphology, color feature and edge detection. It consists of two parts on raw location of license plate and refined location of license plate. In the raw location part, resize the image into the same size, consider the relation of R, G, B components in the image to deal with the noise, detect the edge and use the operations of mathematical morphology repeatedly to obtain the license plate candidate, obtain the raw location by the up-down bound and left-right bound of the license plate. In the refined location part, for the obtained raw location of the license plate, use Radon transformation, edge detection, use the operations of mathematical morphology, find the up-down bound and left-right bound so that the refined location of the license plate is obtained. It is shown that the proposed method is suit for the Chinese license plate with white character and blue background.
