Image Enhancement Based on Histogram Equalization

Abstract

Image enhancement is an important technology in the process of image processing. It can improve the image effect, enhance the overall brightness and clarity of the image. Histogram equalization is a very effective image enhancement technology. On the basis of probability theory, it uses gray point calculation to transform histogram. This paper mainly studies the basic theory of histogram equalization for image processing. At the same time, the image is experimentally analyzed by matlab. The results show that histogram equalization can improve the image effect and enhance the contrast of the image.
