colour.difference.delta_E_CAM16SCD#
- colour.difference.delta_E_CAM16SCD(Jpapbp_1, Jpapbp_2)#
Return the difference \(\Delta E'\) between two given Li et al. (2017) CAM16-SCD colourspaces \(J'a'b'\) arrays.
- Parameters:
Jpapbp_1 – Standard / reference Li et al. (2017) CAM16-SCD colourspaces \(J'a'b'\) array.
Jpapbp_2 – Sample / test Li et al. (2017) CAM16-SCD colourspaces \(J'a'b'\) array.
- Returns:
Colour difference \(\Delta E'\).
- Return type:
Warning
The \(J'a'b'\) array should have been computed with a Li et al. (2017) CAM16-LCD, CAM16-SCD, or CAM16-UCS colourspace and not with the CIE L*a*b* colourspace.
