Abstract

In this paper, a computer vision system, according to digital image processing methods to recognize car license plate is described. Traffic images are captured by a video camera and digitized in to a computer. Vertical and horizontal line scanning is used. The gray scale in horizontal and vertical lines and a treshold help to find the coordinate of the plate. Chosing a second treshold based on area of the plate make seperation of number and alphabetic characters easy.
