Abstract

Number Plate Recognition became a very important in our daily life because of the unlimited increase of cars and transportation systems which make it impossible to be fully managed and monitored by humans, examples are like traffic monitoring, tracking stolen cars, managing parking toll, red-light traffic violation enforcement, border, and customs checkpoints. Yet it is a very challenging problem, due to the diversity of plate formats, different scales, rotations, and non-uniform illumination conditions during image acquisition. This system is approach based on simple but efficient Sobel edge detection method for plate localization. This approach is simplified to segment all the letters and numbers used in the number plate by using bounding box method character segmentation and then to use Template Matching to recognize of numbers and characters. The concentrate is given to locate the number plate region properly to segment all the numbers and letters to identify each number separately.
