Definition
The dichromatic reflection model is a model that describes light reflected from an object’s surface as a linear combination of two components. These components are the body (diffuse) reflection and the interface (specular) reflection.
Background
Reflection models are used for image analysis and object recognition in computer vision, as well as image rendering in computer graphics. Shafer proposed the dichromatic reflection model for inhomogeneous dielectric materials [1]. The first body reflection component provides the characteristic object color, and the second interface reflection component has the same spectral composition as illumination. Thus, according to the dichromatic reflection model, all color values on a uniform object surface are described as a linear combination of two color vectors: the illumination color vector and the body color vector. Tominaga and Wandell proposed a method for testing the adequacy of the model. They show that under all illumination and...
