Abstract
Optical imaging under water represents an unresolved problem until today. Poor visibility, blurred images and a minor signal-to-noise-ratio are the consequences of absorption, scattering and marine-snow dominating the properties of water. This technical report depicts the reasons for poor image qualities of such imaging systems and provides a mathematical model of radiative transfer under water. With respect to computational performance two efficient approximations of radiative transfer are presented and their advantages and disadvantages discussed. Furthermore computational imaging under water will be discussed from the perspective of image restoration.
