MATLAB Code Implementation for License Plate Recognition

This text describes a license plate recognition technology implementation using MATLAB, where the Sobel operator is employed for edge extraction of license plates. The algorithm works by calculating gradient approximations in both horizontal and vertical directions to highlight region boundaries. Through this method, we can effectively isolate Arabic numeral characters on license plates using morphological operations and contour detection, followed by template matching or machine learning classification for final recognition. This technology finds extensive applications in traffic management systems, automated vehicle identification, and security surveillance, making significant contributions to social development and public safety. The implementation typically involves image preprocessing, edge detection using fspecial('sobel') and imfilter functions, character segmentation through connected component analysis, and recognition via correlation-based matching or neural networks.
