A model for estimating spectral properties of water from RGB images
Henryk Blasinski, John C. Breneman, Joyce Farrell · 2014
This paper presents an underwater image formation model incorporating scatter and spectral absorption curves of pure water and three other particle classes; phytoplankton, non-algal particles and colored dissolved organic matter. We also describe an algorithm allowing to derive these depth dependent curves from a sequence of RGB images of a known target. Underwater images generated using the model closely resemble the experimental ones acquired in a variety of conditions. Similarly, the estimated absorption curves, and relative particle concentrations agree with common sense expectations.
