Computational adaptation model and its predictions for color induction of first and second orders
The appearance of a patch of color or its contrast depends not only on the stimulus itself but also on the surrounding stimuli (induction effects–simultaneous contrast). A comprehensive computational physiological model is presented to describe chromatic adaptation of the first (retinal) and second...

| description | The appearance of a patch of color or its contrast depends not only on the stimulus itself but also on the surrounding stimuli (induction effects–simultaneous contrast). A comprehensive computational physiological model is presented to describe chromatic adaptation of the first (retinal) and second (cortical) orders, and to predict the different chromatic induction effects. We propose that the chromatic induction of the first order that yields perceived complementary colors can be predicted by retinal adaptation mechanisms, contrary to previous suggestions. The second order of the proposed adaptation mechanism succeeds to predict the automatic perceived inhibition or facilitation of the central contrast of a texture stimulus, depending on the surrounding contrast. Furthermore, contrary to other models, this model is able to also predict the effect of variegated surrounding on the central perceived color. |
