Light Source Effects.

Abstract

The perception of surface luster in achromatic singleview images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of the specular component of the surface's reflectance and the illumination. Light source effects are broken down into three catagories according to gross aspects of the physical situation in which they occur, and criteria for detecting the regions they cause are suggested.
