Color-Accurate Underwater Imaging using Perceptual Adaptive Illumination

I. Vasilescu, C. Detweiler, D. Rus
2010 Robotics: Science and Systems VI  
This method dynamically mixes the illumination of an object in a distance-dependent way using a controllable multi-color light source.  ...  Capturing color in water is challenging due to the heavy non-uniform attenuation of light in water across the visible spectrum, which results in dramatic hue shifts toward blue.  ...  The scene was at a distance of 3m. The right image shows a coral formation on a ship wreck in the Grand Cayman with existing white flash (Top) and adaptive illumination (Bottom).  ...
