Abstract

Image enhancement is the technique in which the quality of the picture is improved thereby improving the features of the image and enhances the graphic effect of the image on the observer. This image enhancement strengthens the features of images. It emphasizes the image features like boundaries, disparity so that the image is more useful for scrutiny and training. Some of the Image enhancement operation includes contrast stretching, noise removal, pseudocoloring, noise filtering etc. Underwater images are mainly affected from the problem of meagre color disparity and deprived distinguishability. These issues are due to the smattering of light and deflection of light while moving from scarcer to denser medium. Smattering introduces the obscuring of light and decreases the hue difference. These properties of water in submerged images are due the landscape of the water, flora and fauna present in the water. A number of techniques and approaches are recognized by scholars to resolve the problems in underwater image enhancement. In this paper, various submerged image improvement techniques are studied and tested.
