AUTOMATIC CAR LICENSE PLATE EXTRACTION

License plate extraction is an important stage in the vehicle license plate recognition for an automated transport system. This paper presents a novel and practical license plate extraction algorithm based on the edge statistics and the morphology. The proposed approach can be divided into 4 sections, which are vertical edge detection, Linear Gray - scale Transformation, mathem atical morphology - based license plate extraction. The proposed approach is designed to work in a wide range of acquisition conditions, including unrestricted scene environments, different camera - to - car distances, etc. Under the available database, the aver age accuracy of locating vehicle license plate is 84%
