Car License Plate Checking System Based on Neural Network

Ei Phyo Min

Abstract: The proposed car number plate checking (detection) system plays an important role in Digital Image Processing. Car license checking system is a form of automatic vehicle identification. It is an image processing technology used to identify vehicle by only the car license plates. The proposed system consists of basic operations such as preprocessing and image conversion from RGB to Gray. Then, it segments the metallic car license plate part from the front view of car by region growing in the reduction of searching space for localizing the car license plate. And also it applies morphological operators on same image then extract plate region from image and then character segmentation is performed on extracted License Plate and these segmented characters are recognized using Neural Network. Car license plate checking system is developed using MATLAB. Experiments show that the proposed system can effectively and quickly capture the car vehicle image, detect and recognize, the car license plate whether it is in noisy data, lighting and slightly dark under complicated environment.
