Instead, a more revolutionary approach will be required to make appearance predictions for more complex stimuli in a wider array of viewing conditions. ...
Traditional color appearance modeling has recently matured to the point that available, internationally-recommended models such as CIECAM02 are capable of making a wide range of predictions to within the ...
Since it is appropriate to apply spatial filters in a linear-signal space, they are applied in a linear version of IPT prior to conversion into the non-linear version of IPT for appearance predictions. ...

Subjects set asymmetric color matches between a standard object and a test object that were rendered under illuminants with different spectral power distributions. ...
For the range of illuminants tested, we found that the change in the diagonal elements of the linear transformation was a linear function of the illuminant change. ...
In two of the experimental phases we rendered the objects with the standard illuminant, and in the other two we rendered the objects with a test illuminant. ...

As the core of our adaptive metric is pixel-based, our method is amendable to imagesubsampling, thereby greatly reducing the computational cost. ...

In this paper, we tackle the problems in Monte Carlo rendering by proposing a two-stage denoiser based on the adaptive sampling strategy. ...
In the first stage, concurrent to adjusting samples per pixel (spp) on-the-fly, we reuse the computations to generate extra denoising kernels applying on the adaptively rendered image. ...
Average spp budget was set for adaptive sampling methods, while uniformly sampled images rendered with the same spp were fed to non-adaptive sampling methods. ...
