A Review of Automatic Number Plate Recognition

Automatic Number Plate Recognition (ANPR) is a tool that can be used not only at toll booths on highways, expressways, etc. to speed up the process of toll collection but also by car parking management at malls and movie theaters. With the increase in the number of vehicles, automated systems to store vehicle information are becoming increasingly necessary. Communication is critical for traffic management and crime reduction, and it cannot be overlooked. Automatic vehicle identification using number plate recognition is a reliable method of identifying vehicles. It requires a lengthy time and a lot of practice to develop satisfactory results using present algorithms that are based on the idea of learning. Automatic Number Plate Detection is a unique application in machine learning as it detects images and converts them to text form. The algorithm detects and captures the vehicle image and extracts the vehicle number plate using image segmentation. The extracted image is later sent to optical character recognition technology for character recognition. This system is implemented in areas like traffic surveillance, military zones, and apartments.
