Abstract

Introduction: The number of vehicles is increasing day by day in our life. The vehicle may violate traffic rules and cause accidents. The Automatic Number Plate Detection System (ANPR) plays a significant role to identify these vehicles. Number plate detection is very difficult sometimes because each country has its own format for representing the number plate and font types and sizes may also vary for different vehicles. A number of ANPR systems are available nowadays but still, it is a big problem to detect the number plate correctly in various scenarios like in a high-speed vehicle, number plate language, etc.

Methods: In the development of this method, we mainly used wiener filter for noise removal, morphological operations for number plate localization, connected component algorithm for character segmentation, and template-based matching for character recognition.

Results: Our proposed methodology is providing promising results in terms of detection accuracy.

Discussion: The Automatic Number Plate Detection System (ANPR) has a wide range of applications because the license number is the crucial, commonly putative and essential identifier of motor vehicles. These applications include ticketless parking fee management, parking access automation, car theft prevention, security guide assistance, motorway road tolling, border control, journey time measurement, law enforcement, etc.

Conclusion: In this paper, an enhanced approach of automatic number plate detection system is proposed using some different techniques which not only detect the number plate of the vehicle but also recognize each character present in the detected number plate image.

Keywords: Automatic number plate recognition (ANPR), Morphological operations, Weiner filter, Grey image, Edgedetection, Contrast adjustment, Character segmentation and recognition
