A license plate detection algorithm using edge features

Abstract

License Plate Detection (LPD) is a main step in an intelligent traffic management system. Based on many techniques have been proposed to extract license plate of different vehicles in different condition. Finding a technique that provides a good accuracy with a good time response time is difficult. In this paper, we propose a technique for LPD. The proposed technique uses the edge features to find the rows position of the license plate. In order to find the column positions, we find the small blue color part at the left of the license plates in the determined rows position. Our experimental results for different image database show that an accuracy of 96.6 percent can be achieved. © 2012 Springer-Verlag GmbH.
