Shadow Removal

Flash/No-flash Image Pairs

Sunlight produces a shadow.	Flash removes part of the shadow.	The difference, (Both-Ambient)== Pure_Flash_Image has no ambient-shadow, but has added flash-shadows.	Copying edges inside ambient-shadow, from pure-flash image into ambient image, removes all shadows.

Detecting Illumination in Images (Chromagenic Images)

Two images are taken of each scene: a normal one and one with a filter placed in front of the camera.	Results.

Specularity and Shadow Interpolation

Multiple images are taken from a fixed viewpoint, different lights (HP idea).	Generate new, interpolated image for non-measured, new, lighting direction (note: this is non-trivial!).
