Abstract

This paper proposes a spatio-spectral imaging device to simulate and acquire color images under different geometries of illumination. The method allows image analysis and synthesis, even for rough-textured surfaces, under different directions of the incident illumination. In addition the use of the albedo instead of directly the RGB information helps to avoid any shadows or highlights that might falsify results. For accurate color reproduction under uncontrolled illumination conditions an RGB digital camera is used in combination with a 4-sourcebased photometric stereo algorithm to estimate the normals at each image point and the albedo of the surfaces at each pixel. The experimental results show good colorimetric accuracy in the color reproduction of artificial texture objects.
