Abstract
This paper describes a method for estimating the surface spectral reflectance function of inhomogeneous objects. The standard reflectance model for inhomogeneous materials suggests that surface reflectance functions can be described as the sum of a constant (specular) function and a subsurface ( diffuse) function. First we present an algorithm to generate an illuminant estimate without using a reference white standard. Next we show that several physical constraints on the reflectance functions can be used to estimate the subsurface component. A band of the estimated spectral reflectance functions is recovered as possible solutions for the subsurface component.
