colour.difference.delta_E_CAM02SCD#
- colour.difference.delta_E_CAM02SCD(Jpapbp_1: ArrayLike, Jpapbp_2: ArrayLike) NDArrayFloat [source]#
Return the difference \(\Delta E'\) between two given Luo et al. (2006) CAM02-SCD colourspaces \(J'a'b'\) arrays.
- Parameters:
Jpapbp_1 (ArrayLike) – Standard / reference Luo et al. (2006) CAM02-SCD colourspaces \(J'a'b'\) array.
Jpapbp_2 (ArrayLike) – Sample / test Luo et al. (2006) CAM02-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 Luo et al. (2006) CAM02-LCD, CAM02-SCD, or CAM02-UCS colourspace and not with the CIE L*a*b* colourspace.
