A Review on Underwater image enhancement

Abstract: Image enhancement technique is one of the widely used techniques to improve the image quality by enhancing the visibility of the images. This paper presents several image enhancement techniques. These techniques have been developed in a number of applications such as underwater images, medical images etc. Due to light absorption, light reflection, bending of light and scattering of light or poor visibility of underwater images, there is need to improve the quality of an underwater image. This paper ends with the certain limitations of existing techniques.
