(a): Radar range image.
(b): Lambertian surface with surface reflectance of
16 Macbeth patches, simultaneously
illuminated by three illuminants.
(c): White Lambertian sphere in same lighting. Symbols r,g,b
mark location of maxima in R, G, and B channels.
(a): Three illuminants. Equi-energy white light is also shown.
(b): Camera sensitivities.
(c): Sharpened camera sensitivities.
(a): Pixels self-shadowed from at least one light.
(b): Pixels with solutions for ratios
(a): Recovered normals, shaded from (0,0,1).
(b): Ground truth normal vectors, also shaded from (0,0,1).
(a): Recovered surface with recovered color as seen under white
(b): Ground truth surface and colors under white light.
associated with a particular RGB point, with four
solutions for normal vector equal to a given vector divided by
the ellipsoid coordinates.
