Abstract

Underwater images suffer degradation as a result of the noise introduced by the water column between the object and the imaging device. This noise includes such problems as suspended particle scattering and unequal spectral attenuation. These result in a significant degradation of the image. The problem is compounded by the requirement of artificial illumination. Model based attacks on this problem are presented with particular attention being given to illumination models.
