Design of car license plate area detection algorithm for enhanced recognition plate

Abstract

The high penetration rate of cars in Korea causes a great deal of congested traffic, and a variety of car management systems which use license plate detection technology are being employed to overcome this problem. However, detection errors occur in existing edge-based license plate detection technology due to a low license plate area recognition rate. Therefore, in this paper we have designed a car license plate area detection algorithm which improves the recognition rate through an operation which combines canny and Laplacian edges in order to improve the license plate recognition rate.
