A Survey on Underwater Image Processing Techniques

Abstract

Images taken underwater generally suffer from various forms of degradation due to the effects of absorption, light scattering due to suspended particles, presence of background light, low light, et cetera. Over the years, researchers have put forth various underwater image enhancement and image restoration techniques to improve the conditions of these images to assist in the examination and analysis of marine lifeforms and underwater objects. This paper aims to provide a summary and analysis of a few recent existing underwater image enhancement and image restoration techniques that were put forth in the past six years. Also, the performance of a few of the methods was evaluated both subjectively and objectively.
