The assumed light direction for perceiving shape from shading
Recovering 3D shape from shading is an ill-posed problem that the visual system can solve only by making use of additional information such as the position of the light source. Pr...

Color rendering indices in global illumination methods
Human perception of material colors depends heavily on the nature of the light sources that are used for illumination. One and the same object can cause highly different color impr...
