MATLAB Program for License Plate Localization in License Plate Recognition Systems

This MATLAB program implements license plate localization for license plate recognition systems. License plate localization serves as a fundamental step in such systems, involving analysis of image characteristics to identify license plate positions. The program leverages MATLAB's image processing toolbox and implements algorithms including edge detection, morphological operations, and region analysis to accurately locate license plates within vehicle images. Key functions likely involve image preprocessing (conversion to grayscale, noise reduction), feature extraction (edge detection using Sobel/Canny operators), and candidate region selection based on aspect ratio and geometric properties. This implementation helps users quickly and accurately identify license plate regions, providing a solid foundation for subsequent character segmentation and recognition stages. To utilize this program, users must have MATLAB installed and possess basic knowledge of image processing and programming concepts. After execution, users obtain license plate localization results and can further optimize parameters such as threshold values or morphological structuring elements based on specific image conditions to improve detection accuracy under varying lighting and environmental conditions.
