colour.recovery.MSDS_GAUSSIAN_BASIS

colour.recovery.MSDS_GAUSSIAN_BASIS = MultiSpectralDistributions(name='Gaussian Basis', ...)

Gaussian basis multi-spectral distributions for spectral upsampling.

The basis spectra use clamped Gaussians with parameters optimized for round-trip colorimetric accuracy with sRGB primaries:

• Red: Gaussian clamped flat toward long wavelengths

• Green: Symmetric Gaussian

• Blue: Gaussian clamped flat toward short wavelengths

• Cyan: Independent Gaussian clamped flat toward short wavelengths

• Yellow: Independent Gaussian clamped flat toward long wavelengths

• Magenta: Inverted Gaussian (valley at green wavelengths)

• White: Constant value of 1

Parameters can be recomputed using optimise_gaussian_basis_parameters().
