Survey on Underwater Image Enhancement

This survey paper deals with the methods to improve the visibility range of underwater image enhancement techniques. Normally underwater images are suffered by several factors like light scattering, color absorption, color change these leads to poor visibility and low contrast of an underwater images. Techniques used in an image enhancement are different due to the underwater environment distortions when compared to the normal image enhancement method. To rectify the problems in underwater images number of existing system is available in the survey of underwater image processing.
