Colour difference data sets and performance of colour difference formulae

Properties for adjacent and separated samples and for small and large differences

Figures and data of "Colour difference data sets and performance of colour difference formulae" are in the folders YEXX (colour series Y, E=English, XX=00 to 99).

Folder and Title
Development of colour difference data sets
Many of the folders XEXX (XX=00 to 99) include colour difference data sets in the PS files. The files create a standard PDF output format which is used as standard input format in the folders YEXX (XX=00 to 99).
In the folders XEXX (XX=00 to 99) the input data of the colour difference data sets are from different sources. Any data set is described by 8 characters, for example OS_L0128.
1. O is for the name OSA, M is for the name Munsell, etc.
2. A or S describes the sample viewing condition: Adjacent (A) or Separate (S).
3. V, T, S, L, E is for the size of the mean colour difference in the data set
- V = VTCD Visual Threshold Colour Differences (0 < dE*ab <= 1)
- T = TCD Threshold Colour Differences (0 < dE*ab <= 2)
- S = SCD Small Colour Differences (0 < dE*ab <= 5)
- L = LCD Large Colour Differences (5 < dE*ab <= 20)
- E = ELCD Extra Large Colour Differences (20 < dE*ab <= 99).
4. 0, W, V, C, or D (0 = no pair comparison data used, or data from WANG or VIK experimental data used, or data from CIELAB or CIEDE2000 formula used).
5-8. number of colour difference pairs in the data set.


For basic information on colour, see also the booklet Colour and Colour Vision - Elementary Colours in Image Technology
in 6 languages: English, German, French, Spanish, Italian, and Norwegian (2015, 85 pages, 2,5 MB, PDF, format A5 also for mobil reading).
