Chapter D: Colour Appearance, Elementary Colours, and Metrics, Image part DEAS

Title: Colour metrics for light and colour as function of the relative luminance L/Lu (Lu=surround luminance)
Experimental data and model functions Q/Fab(xr).
1. Introduction and goals.
2. Experimental data from a book for xr=log(L/Lu);
3. Response functions Q/Fab[e^(xr/a) or 10^(xr/a')] with a'=a ln(10).
4. Deviations of the response functions for luminance discrimination.
5. Antichromatic models of colour vision.
6. Receptor sensitivity for achromatic colours.
7. Logarithmic and linear models for combinations of the sensitivities.
