Extraction of vehicle number plates using edge detection and morphological operations

This paper presents a methodology for extraction of the vehicle number plates from the vehicle images using edge detection techniques. The main idea is to use different morphological operations in such a way so that the number plate of the vehicle can be identified precisely. The methodology makes the task of extraction of the number plate independent of color, size and location of number plate. This algorithm can quickly and correctly detect the number plate area from the vehicle image in any direction but there is sufficient light on fall on number plate.
