متن کاملThe Effect of DLP Projector White Channel on Perceptual Gamut
The effect of white channel enhancement as implemented in the Texas Instrument DLP digital projector technology is evaluated theoretically using both the CIELAB and the CIECAM02 color appearance models and experimentally through psychophysical testing using real images. Both theory and the test results confirm a compression of perceptual gamut in both chroma and colorfulness as a result of the ...

Rodney L. Heckaman Mark D. Fairchild Abstract — The effect of white-channel enhancement as implemented in the Texas Instrument DLPTM digital projector technology is evaluated theoretically using both the CIELAB and the CIECAM02 color appearance models and experimentally through psychophysical testing using real images. Both theory and test results confirm a compression of perceptual gamut in bo...
متن کاملSpectral-reflectance function recovery for improved colour-constancy experiments
A set of symmetric memory-matching data is presented to analyse some implications of long-term memory factors within classical colourconstancy paradigms and separation algorithms. Using simulated Mondrian-type colour surrounds on a CRT monitor, subjects make a series of colour matches between a test and a matching surface; the surfaces are rendered under the same standard illuminant (equal-ener...
متن کاملImproving Spectral Reflectance Reconstruction Accuracy using Bootstrap
The idea p esented in this paper elates with the generalisation abilities of existing learning-based or indirect spectral eflectance econstruction methods, which use a priori information about the objects to be imaged. Researchers using this type of methods have characterised and compared their errors over different test sets. However, they do not treat the problem of how to increase the result...
