In Shafer's dichromatic reflection model, scene radiance has two components:
- λ is: the: wavelength,
- cb is the——body (diffuse) reflected component,
- cs is the surface (interface) (specular) 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※
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."
