Design and Implementation of Vehicle Licence Plate Recognition Based on Matlab
Abstract: Vehicle license plate recognition is an important area of research on image recognition. Some license plate recognition technologies in the image preprocessing such as license plate localization, character segmentation and character recognition are studied based on MATLAB. The capability of vehicle plate recognition is improved by integrating a variety of methods, and some problems such as locating the regional segmentation license, segmentating license plate character and extractiing characters in the natural background are resolved. Through a number of license plate image processing, the results show that the license plate recognition method based on MATLAB is successful and effective.
