Research on an Efficient Method of License Plate Location

Abstract

Abstract In the application of intelligent transportation system (ITS), license plate (LP) location is one of the most crucial step. In view of illumination variance, noise, complex and dirty background, this paper presents a license plate location method, which based on edge information analysis with a preprocessing technique. License plate area contains rich edge and texture information, which can be used to detect a number plate location. Experimental results demonstrated the great robustness and efficiency of our method.
