Under-water image enhancement algorithms: A review.

Submarine cameras are commonly used to track and observe the seabed. They are often used in under-water robotics, marine exploration and oceanography. The under-water cameras face several faces due to under-water optics. As the light travelling through the water is absorbed and scattered due to small particles that brings noise in the captured images. Many approaches have been suggested over the past five years to solve the conventional problems of under-water imaging. This review paper deals with under-water image enhancement (UIE) methods and existing dataset. At last discussion on the identified gaps is included that will help the researchers to overcome the gaps identified. [ABSTRACT FROM AUTHOR]
