Why no love for Luv?
I’ve always liked looking at colors and color relationship in both CIEL*a*b* and CIEL*u*v*. Neither is perfectly perceptually uniform, and on average, they’re both about the same distance away from that. A couple to times I’ve looked at averaging the two, but nobody else does that, so I haven’t published any of those graphs. But… [Read More]
Gamut of a basis-function derived metamer set
I’ve previously reported on a project about observer metameric errors in digital cameras. I built a program that, given a target color and a set of sample reflectance spectra, will: Using principal component analysis, find a set of basis functions for the sample set Assuming the set is lit with a particular illuminant (I… [Read More]
Observer metameric error in simulated cameras, part 3
In previous work for a project about observer metameric errors in digital cameras, I built a program that, given a target color and a set of sample reflectance spectra, will: Using principal component analysis, find a set of basis functions for the sample set Assuming the set is lit with a particular illuminant (I used… [Read More]
