colour.CAM02SCD_to_JMh_CIECAM02(Jpapbp: ArrayLike) → numpy.ndarray[source]¶

Convert from Luo et al. (2006) CAM02-SCD colourspace \(J'a'b'\) array to CIECAM02 \(JMh\) correlates array.

Parameters: Jpapbp (ArrayLike) – Luo et al. (2006) CAM02-SCD colourspace \(J'a'b'\) array.
Returns: CIECAM02 correlates array \(JMh\).
Return type: numpy.ndarray

Notes

SCD in CAM02-SCD stands for Small Colour Differences.
