Contrast Enhancement Based on Fusion Method: A Review

Image enhancement is a fundamental step and plays an important role in image processing, pattern recognition, and computer vision. Image enhancement can sharpen the edges of objects in an image, making it easier to extract objects and attain more information from the enhanced image. In this paper, a few popular image enhancement methods based Fusion Method was studied. This paper presents an exhaustive review of these studies and suggests a direction for future developments of image enhancement methods. Each method shows the owned advantages and drawbacks. In future, this work will give the direction to other researchers in order to propose new advanced enhancement techniques.
