A special technique for digital polarization images treaty is presented in detail. This technique is used for Earth surface remote sensing purposes and deals with the full Stokes vector analysis of light reflected from surface. The underlaying surface is modeled as a little anisotropy absorption medium. The accuracy characteristics of the proposed method on the base or real digital images are presented. Specific limitations of technique for polarization digital images treaty in visible are considered. The ability of this technique usage to SAR polarization images treaty is also discussed. The main requirements for obtaining radar polarization images are proposed.
