Fast color-space decomposition based environment matting
Biswarup Choudhury, Deepali Singla, Sharat Chandran · 2008
In the literature, environment matting (EM) refers to the complex process of discovering how light in an environment interacts with an object; notably, it may transfer through a transparent object, and undergo scattering. Modeling the 3D geometry, and the index of refraction, of non-uniformly optically active substances is intractable; therefore image-based frameworks are useful. The most convincing techniques use a large number of (monochrome, or two-tone) probing images to extract the matte.
