Research on Fast Localization Algorithm of Low-Quality License Plate Images

Abstract:

This article introduces a vehicle license plate localization method which is based on gray image. This method mainly processes some uneven illumination and low-quality vehicle images. Firstly it uses edge detection operators to enhance images to plate region. Then it enhances with algorithm such as binaryzation, first-order points difference and median filtering in custom templates. And lastly it makes it more accurately in license plate localization through projection method enhancement. It is showed in experiments that this method can license plate localizes these kinds of low-quality license plate images accurately and effectively.
