Colour vision and Colorimetry (2020), Image part BEVS

Title: Colour thresholds and line elements in 10 colour spaces
IECsRGBu0 to 9 with additional function data
1. Introduction and goals;
2. Modifications IECsRGBu0 to 9 of the colour space IECsRGB, similar to CIELAB;
3. Corresponding line elements for the experimental contrast Y/(delta Y);
4. Absolute lightness L* (CIE 15) and T* (IEC 61066-2-1 (sRGB)) 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=50, 1/g=1/2,4, Sd=0.

The following ten pages BEV0 to BEV9 of this chapter
