Determining lightness from an image
BKP Horn - Computer graphics and image processing, 1974 - Elsevier
A method for the determination of lightness from image intensity is presented. For certain
classes of images, lightness corresponds to reflectance, while image intensity is the product …

Computing lightness
G Brelstaff, A Blake - Pattern Recognition Letters, 1987 - Elsevier

A novel algorithm for color constancy
DA Forsyth - International Journal of Computer Vision, 1990 - Springer
Color constancy is the skill by which it is possible to tell the color of an object even under a
colored light. I interpret the color of an object as its color under a fixed canonical light, rather …

“Colour constancy” in Mondrian patterns: A partial cancellation of physical chromaticity shifts by simultaneous contrast
A Valberg, B Lange-Malecki - Vision Research, 1990 - Elsevier
Abstract Edwin Land's Mondrian demonstrations (Land 1977, 1983, 1986a) are striking
examples that the perceived colours of objects are largely independent of the chromaticity of …
