Abstract
Automatic License Plate Recognition (ALPR) systems are important in Intelligent Transportation Services (ITS) as they help ensure effective law enforcement and security. These systems play a significant role in border surveillance, ensuring safeguards, and handling vehicle-related crime. The most effective approach for implementing ALPR systems utilizes deep learning via a convolutional neural network (CNN). A CNN works on an input image by assigning significance to various features of the image and differentiating them from each other. CNNs are popular for license plate character recognition. However, little has been reported on the results of these systems with regard to unusual varieties of license plates or their success at night. We present an efficient ALPR system that uses a CNN for character recognition. A combination of pre-processing and morphological operations was applied to enhance input image quality, which aids system efficiency. The system has various features, such as the ability to recognize multi-line, skewed, and multi-font license plates. It also works efficiently in night mode and can be used for different vehicle types. An overall accuracy of 98.13% was achieved using the proposed CNN technique.
Highlights
Intelligent Transportation Systems (ITS) [1] have undergone significant development over the past few decades
Since the execution of the Automatic License Plate Recognition (ALPR) system demands specific types of vehicle images, a folder named “images” was created in the current directory, which consisted of 160 images with all types of vehicles, multi-line license plate images, multi-font license plate images, images captured in different illumination conditions
The current era is witnessing a tremendous increase in population growth, which has resulted in many more vehicles being on the roads
Summary
Intelligent Transportation Systems (ITS) [1] have undergone significant development over the past few decades. These systems are designed and used to enhance the movement of traffic. They aid in minimizing the adverse impact of vehicles on the environment. They gather all the data related to a vehicle to support a real-time monitoring mechanism [2]. A significant component of ITS is an automatic license plate recognition system. Each vehicle has a license plate with a unique identification number that is used for recognition purposes so that no tags, external
