License Plate Recognition (LPR) is an image-processing technology used to identify vehicles by their license plate. This technology is gaining fame in security and traffic installations. It has many applications in parking, access control, tolling, border control, stolen cars identification, enforcement, traffic control etc. The input to the License Plate Recognition system is a coloured image of the license plate and the output is the registration number of the vehicle which is alphanumeric characters.
