Dichromatic reflectance model

Dichromatic reflectance model

In Shafer’s dichromatic reflection model, scene radiance has two components:

 L(\lambda) = m_\mathrm{b} c_\mathrm{b}(\lambda) + m_\mathrm{s}c_\mathrm{s}(\lambda) \,
cb is the body reflected component
cs is the surface reflected component
mb and ms are scale factors depending on illumination, view directions and surface orientation.
