Colour vision and Colorimetry (2020), Image part BEXS

Title: Colour thresholds and line elements in 10 colour spaces
CIELABu0 to 9 with additional function data
1. Introduction and goals;
2. Modifications CIELABu0 to 9 of the colour space CIELAB;
3. Corresponding line elements for the experimental contrast Y/(delta Y);
4. Absolute lightness L* (CIE 15) and T* (ISO/CIE 11664-4 (CIELAB)) and relative lightness l* and t*;
5. Logarithmic and linear figures for L*, T*, l* and t*;
6. Logarithmic figures for threshold delta Y, sensitivity (delta Y)/Y, and contrast Y/(delta Y);
7. Parameters of the formula T*=Sn(Y/Yu)^(1/g)-Sd with Yu=18,
for exaample Sn=66, 1/g=1/3,0, Sd=16.
