Diagonal transforms suffice for color constancy

GD Finlayson, MS Drew, BV Funt - 1993 (4th) International …, 1993 - ieeexplore.ieee.org
The main result is to show that under the conditions imposed by the Maloney-Wandell color
constancy algorithm, color constancy can be expressed in terms of a simple independent
adjustment of the sensor responses, so long as the sensor space is first transformed to a
new basis. The overall goal is to present a theoretical analysis connecting many established
theories of color constancy. For the case where surface reflectances are two-dimensional
and illuminants are three-dimensional, it is proved that perfect color constancy can always …
