The goal of spectral modelling is to artificially generate a spectrum with properties that resemble those met in nature. We additionally require, that the likelihood of a spectrum to be generated is equal to the likelihood for such spectrum to be in nature. To the best of our knowledge, there is no research yet, that pursues the latter. Related problems to spectral modelling are spectral recovery and generation of metameric spectral power distributions (SPDs). An SPD is a combination of a reflectance spectrum and an illuminant: S() = R()I(). Given a color as an XYZ tristimulus which is induced by an object and an illuminant I(), the problem of spectral recovery is to recover a reflectance spectrum R() of the object. In the problem of generation of metameric SPDs it is needed to produce SPDs which induce a given XYZ tristimulus.
