Relevant Techniques for License Plate Detection and Recognition

License Plate Detection and Recognition Techniques: A gradient enhancement method is proposed to strengthen image edges through simple gradient transformations that highlight edge information, combined with dilation operations from mathematical morphology for rapid license plate localization. In the character segmentation phase, the minimum area rotation method determines the optimal license plate rotation angle, followed by vertical projection analysis to segment individual characters. Implementation involves gradient calculation algorithms like Sobel/Prewitt operators and morphological structuring elements for dilation.
