| Abstract: | The License Plate Recognition System (LPR) is introduced first, then focused is on the key techniques of this system and a easy method to realize this system . The gray levels between the license character and the background are used to segment the license plate from the original gray image. A method of projection is used to segment the characters,and the hierarchical contour features of the characters is used to recognize the characters systematically. |
