Abstract

In order to improve image quality in image processing, image enhancement method plays a very important role. This paper makes an exhaustive study of some enhancement methods such as contrast enhancement, image smoothing and image sharpening. And these methods are applied to License plate recognition. Various basic image enhancement techniques of License Plate Recognition are discussed and simulated with MATLAB. Through a lot of experiments, an improved image enhancement method is proposed by combining histogram equalization and median filtering. Comparing various image enhancement methods, the improved method can efficiently avoid interfere and enhance the contrast of image and obtain satisfying effects.
