  text: The reflectance field of a face describes the reflectance properties responsible
    for complex lighting effects including diffuse, specular, inter-reflection and
    self shadowing. Most existing methods for estimating the face reflectance from
    a monocular image assume faces to be diffuse with very few approaches adding a
    specular component. This still leaves out important perceptual aspects of reflectance
    as higher-order global illumination effects and self-shadowing are not modeled.
    We present a new neural representation for face reflectance where we can estimate
    all components of the reflectance responsible for the final appearance from a
    single monocular image. Instead of modeling each component of the reflectance
    separately using parametric models, our neural representation allows us to generate
    a basis set of faces in a geometric deformation-invariant space, parameterized
    by the input light direction, viewpoint and face geometry. We learn to reconstruct
    this reflectance field of a face just from a monocular image, which can be used
    to render the face from any viewpoint in any light condition. Our method is trained
    on a light-stage training dataset, which captures 300 people illuminated with
    150 light conditions from 8 viewpoints. We show that our method outperforms existing
    monocular reflectance reconstruction methods, in terms of photorealism due to
    better capturing of physical premitives, such as sub-surface scattering, specularities,
    self-shadows and other higher-order effects.
