A Simple and Effective Method for License Plate Localization

Abstract

Today the world is growing with new advancements and technologies. These new technologies save the processing time that was consumed by doing manually. One of these technologies is automatic license plate recognition that is used in daily life at toll bars, parking, security, criminal case, and so on. License plate recognition consists of three main stages—plate localization, plate segmentation, and character recognition. Among these, localization is the performance enhancement stage as if the plate is not localized accurately then how the plate will get segmented and how the characters on the plate will be recognized. So, localization must be accurate for an efficient recognition. In this article, the localization is done by filling the holes in an image after edge detection using MATLAB. This method achieved a good accuracy.
