Illumination Demultiplexing from a Single Image
A class of techniques in computer vision and graphics is based on capturing multiple images of a scene under different illumination conditions. These techniques explore variations...

Illuminating triangles and quadrilaterals with vertex floodlights
We show that three /6 vertex floodlights suffice to illuminate any triangle, and we prove that any quadrilateral can be illuminated by three /4 vertex floodlights.

(De) Focusing on Global Light Transport for Active Scene Recovery
Most active scene recovery techniques assume that a scene point is illuminated only directly by the illumination source. Consequently, global illumination effects due to inter-refl...

Photometric Stereo with Nearby Planar Distributed Illuminants
This paper considers the problem of shape-from-shading using nearby planar distributed illuminants. It is shown that a rectangular planar nearby distributed uniform isotropic illu...

Illumination transfer using homomorphic wavelet filtering and its application to light-insensitive face recognition
In this paper, we propose a novel homomorphic wavelet filtering based illumination transfer technique to change the dominant lighting of one face image (source face image) to anot...
