LICENSE-PLATE_1
The ANPR (Automatic Number Plate Recognition) using ALR (Automatic line
Tracking Robot) is a system designed to help in recognition of number plates of vehicles.
This system is designed for the purpose of the security and it is a security system. This
system is based on the image processing system. This system helps in the functions like
detection of the number plates of the vehicles, processing them and using processed data for
further processes like storing, allowing vehicle to pass or to reject vehicle. This system also
helps to conduct the graphic images of the vehicles which can be further stored in the
database in text format reducing size of data to be stored.
