An Effective Image Enhancement Method for Color Fundus Images

Published: 25 February 2022 Publication History

Abstract

A method is proposed for adaptive fundus image enhancement so as to restore the color images that are with extremely low or nonuniform brightness. Our proposed method is capable of increasing the brightness, contrast of images without losing original color hue. It includes three steps: luminance enhancement, contrast improvement, and color restoration. All procedures are adapted and modified from conventional image processing algorithms, which are proved simple and less time-consuming. Two public and commonly used fundus image database were partially employed to evaluate the performance of our method. It is concluded that the brightness of images was enhanced by 86.35 % and the contrast was improved by 132.37 % without color distortion.
