title: Criteria for color constancy in trichromatic bilinear models.
abstract: We examine conditions under which the spectral properties of lights and surfaces may be recovered by a trichromatic visual system that uses bilinear models. We derive criteria for perfect recovery, formulated in terms of invariant properties of model matrices, for situations in which either two or three lights are shown sequentially on a set of surfaces.
