Waves on the water surface create spatio-temporal illumination patterns underwater. Concave regions on the surface diverge light rays refracting into the water, while convex regions create convergence of rays (caustics). Therefore, the natural illumination of underwater objects is spatially varying. Moreover, in shallow water this nonuniform intensity distribution varies significantly in time, as the water surface changes with the wave motion. In this paper we present a method that attenuates… CONTINUE READING
