License Plate Recognition

Abstract

License plate detection is important and fastest growing technology in Intelligent Transportation System
(ITS).The license number can be detected by various techniques like by using Artificial neural networks, plate
localization and feature extraction and other basic image processing techniques. In this paper we perform Optical
Character Segmentation (OCR) on the captured image. Different steps of OCR viz. gray scaling, blurring, thresholding,
segmentation are applied on the image. Through template matching, the characters on the number plate are matched
with the template characters stored on the local database. Finally the character numbers are recognized. The de tected
number is used for checking the billing account of user vehicle at toll plazas. Thus the application of license plate
recognition is applied for maintaining the records and billing at tolls.
