Abstract: Intelligence surveillance is an important commodity in traffic based system. Automatic License Plate Recognition (ALPR) is a challenging area of research. This works deals with problems related to artificial intelligence , neural networks and machine vision in the construction of an automatic license recognition (ALPR)system. These intelligence system helps in traffic monitoring during rush hours, road safety and commercial applications like car parking lots and law enforcements .In this paper a license plate recognition system is proposed which uses captured digital image of front or rear of the vehicles and can be easily applied to commercials car park systems to access the parking spaces and also it prevent car theft issues.
