Dichromatic reflectance model
In Shafer’s dichromatic reflection model, scene radiance has two components:
- cb is the body reflected component
- cs is the surface (interface) reflected component
- mb and ms are scale factors depending on illumination, view directions and surface orientation.
Separation algorithm
BREN (body reflection essence-neuter) model based[1]
Body essence is an entity invariant to interface reflection, and has two degrees of freedom. The Gaussian coefficient generalizes a conventional simple thresholding scheme, and it provides detailed use of body color similarity.[1]
