colour.characterisation.optimisation_factory_rawtoaces_v1¶

colour.characterisation.optimisation_factory_rawtoaces_v1()[source]¶

Factory that returns the objective function and CIE XYZ colourspace to optimisation colourspace/colour model function according to RAW to ACES v1.

The objective function returns the euclidean distance between the training data RGB tristimulus values and the training data CIE XYZ tristimulus values** in CIE L*a*b* colourspace.

Returns: Objective function and CIE XYZ colourspace to CIE L*a*b* colourspace function.
Return type: tuple
