colour.characterisation.apply_matrix_colour_correction_Vandermonde#

colour.characterisation.apply_matrix_colour_correction_Vandermonde(RGB: ArrayLike, CCM: ArrayLike, degree: int = 1) → NDArrayFloat[source]#

Apply given colour correction matrix \(CCM\) computed using Vandermonde method to given RGB colourspace array.

Parameters:

  • RGB (ArrayLike) – RGB colourspace array to apply the colour correction matrix \(CCM\) to.

  • CCM (ArrayLike) – Colour correction matrix \(CCM\).

  • degree (int) – Expanded polynomial degree.

Returns:

Colour corrected RGB colourspace array.

Return type:

numpy.ndarray
