Arutz Sheva: new technique "drastically" improves underwater photos  
Wednesday, September 8, 2004 | by Eamon Hickey

Arutz Sheva reports that a professor named Yoav Schechner of the Faculty of Electrical Engineering at the Technion-Israel Institute of Technology in Haifa, Israel has developed a technique to dramatically improve the clarity of underwater photographs.

Shechner's method involves the use of a normal polarizing filter at the time of image capture combined with a software post-processing step that uses an algorithm developed by Schechner and graduate student Nir Karpel. The technique supposedly counteracts the veiling effect of "backscatter", the scattering of ambient light that occurs in water.

The algorithm at the heart of this technique is apparently not currently publicly available, but this story notes that Schechner is seeking ways to commercialize the discovery.
