This paper presents a review of underwater image enhancement techniques which serves as the foundation of a variety of underwater imaging applications including the study of aquatic life forms, underwater object detection and classification or simply an improvement in the appearance of underwater images.Unlike regular imaging in a normal environment, underwater imaging suffers from reduced clarity, entailed by scattering and absorption of light.There are regions with non-uniform illumination and prominent bluish and greenish tones depending on the wavelength of light.The quality of underwater images also depends on the photographic device used to capture the image, turbidity of water.This paper discusses the different types of enhancement brought about by varied underwater image enhancement techniques.
