Colour Naming, a full parametric model has been defined on the CIE Lab space. It is given as 11 memberships functions for the basic color terms.


Colour-Texture perception, spatio-chromatic interaction is modelled as the induction mechanisms of the human visual system. A computational model for brightness induction based on a multi-resolution wavelet predicts brightness induction in the following visual illusions

Colour sharpening, perceptual mechanisms are implemented to build enhanced versions of colour images
