Abstract

Image configurations that are judged transparent can arise from a number of different physical sources, such as the multiplicative processes of shadowing or filter attenuation or the additive processes of scattering or specular reflection. Nonetheless, the transparent interactions have certain computational commonalities, which may allow images to be analyzed with a "prephysical" representation that contains information about the ordering of a series of image layers, along with a set of constraints on the optical interaction between layers.
