Abstract
We propose a perceptual chromatic adaptation transform for white balance that
makes use of split-quaternions. The novelty of the present work, which is
motivated by a recently developed quantum-like model of color perception,
consists at stressing the link between the algebraic structures appearing in
this model and a certain sub-algebra of the split-quaternions. We show the
potentiality of this approach for color image processing applications by
proposing a chromatic adaptation transform, implemented via an appropriate use
of the split-quaternion multiplication. Moreover, quantitative comparisons with
the widely used state-of-the art von Kries chromatic adaptation transform are
provided.
