colour_correction_matrix_Vandermonde
(M_T, M_R, degree=1)[source]¶ Computes a colour correction matrix from given \(M_T\) colour array to \(M_R\) colour array using Vandermonde method.
- Parameters
M_T (array_like, (n, 3)) – Test array \(M_T\) to fit onto array \(M_R\).
M_R (array_like, (n, 3)) – Reference array the array \(M_T\) will be colour fitted against.
degree (int, optional) – Expanded polynomial degree.
- Returns
Colour correction matrix.
- Return type
ndarray, (n, 3)
