文章摘要: In order to reduce the complexity of image recognition and improve the recognition speed for license plate, the gray of the plate image is adjusted before the image recognition. The binary image of license plate is characterized and contrasted with the rotated binary image, and the various uncertainties could be proposed by means of Fourier transform algorithm. By using Fourier descriptors, the standard characteristic Fourier descriptors of license plate could be extracted. The characters of license plate could be recognized and positioned through the feature extraction and matching process of license plate. Key words: Digital image, Fourier descriptors, License plate recognition
