A vehicle license plate recognition system based on fixed color collocation

Locating the region of license plate is the key of the vehicle plate recognition system. A new method is adopted in this paper instead of the traditional method based on gray image. The method that sufficiently utilizes the color characteristics of the colored image is based on the color collocation of the plate's background and characters combined with the plate's structure and texture to locate the vehicle license plate. Then the plate's region would be binarized, segmented and recognized. The recognition rate reaches 95% by experiments.
