Evaluating the Research Gaps of Underwater Image Enhancement Techniques

Enhancement is among the challenging factors in image processing. The goal of enhancement is to enhance the structural appearance of a picture without the degradation in the input image. The enhancement techniques make the identification of key features easier by eliminating noise and other artifacts within an image. In this paper, we present an overview of image enhancement processing techniques applied on visibility restoration. More specifically, we categorize processing methods based on representative techniques of Image enhancement
