Title: TUBJND colour vison model: Receptor-response functions Fab(xr)
and derivations F'ab(xr) for different parameters a,b;
Calculations and plots for the colour-difference formula HAULAB
for four adaptation luminances and four viewing angles
1. Introduction and goals.
2. TUBJND colour vison model: receptor-response functions Fab
and derivations F'ab for different parameters a,b.
3. Antagonistic functions Fab and F'ab without a shift.
4. Calculations with the colour-difference formula HAULAB 1980
for 4 adaptation luminances L=300, 1000, 200, 40 cd/m^2
and 4 viewing angles phi=120', 60', 30', 20'/10'.
5. Calculation of log and lin [lightness L*, threshold delta_Y,
sensitivity delta_Y/Y, contrast Y/delta_Y].
6. Application and discussion.

The following ten pages heu0 to heu9 of this chapter
show the content with links to the single figures in up to six formats.
