A new study has used magnetoencephalography to track cortical responses color as they emerge in time. Similarities and differences within these neural parallel characteristics of the perceptual experience color. It is still common describe vision terms two stages. In first, light spectrum sampled by three classes retinal cone receptors with different spectral sensitivities. second, signals are ...

The Beltrami geometrical framework for scale-space flows is generalized to nontrivial color space geometries and implemented in analysis and processing of color images. We demonstrate how various models of color perception, interpreted as geometries of the color space, result in different enhanced processing schemes.
