Although many color constancy methods exist, they are
all based on specific assumptions such as the set of possible
light sources, or the spatial and spectral characteristics of
images. As a consequence, no algorithm can be considered
as universal. However, with the large variety of available
methods, the question is how to select the method that induces
equivalent classes for different image characteristics.
Furthermore, the subsequent question is how to combine the
different algorithms in a proper way.
To achieve selection and combining of color constancy
algorithms, in this paper, natural image statistics are used
to identify the most important characteristics of color images.
Then, based on these image characteristics, the
proper color constancy algorithm (or best combination of
algorithms) is selected for a specific image. To capture the
image characteristics, the Weibull parameterization (e.g.
texture and contrast) is used.
Experiments show that, on a large data set of 11

images, our approach outperforms current state-of-the-art
single algorithms, as well as simple alternatives for combining
several algorithms.
