Automatic Number Plate Recognition Using Smart Phones

Abstract: This work develops a smart phone based system featuring license plate recognition. This system features the detection and recognition of license plate using smart phones. Using smart phone the image of a license plate is taken and the user gets to know whether the license plate is original, it also provides the details of the vehicle and the details of the owner of a vehicle. This system has been combined in three self developed novel methods, those are license plate extraction and segmentation using vertical and horizontal histogram, Ad-Hoc based remote motion control system, character recognition using artificial neural network. After implementation we can show the license plate detection rate and recognition rate of the Smart Phone based System are over 99 % and over 98%, respectively, under various scene conditions. Especially, the execution time of license plate recognition, including license plate detection, is only about few seconds per frame on the Smart Phone-based System. I
