ABSTRACT:
Generation of an Interim Connection Space for spectral data in a full spectral space is provided. A set of linear maps is accessed, each linear map characterizing a linear transformation from the full spectral space to a colorimetric space, and spectral measurement data is accessed. The linear maps can for example be determined by a set of illuminants. The full spectral space is decomposed into a first subspace that minimizes a loss of a spectral component in the spectral measurement data under a projection along a second subspace onto the first subspace. The second subspace is a null subspace of the set of linear maps. The Interim Connection Space is generated based on the first subspace. The Interim Connection Space can include, for example, a linear map characterizing a linear transformation from the Interim Connection Space to the full spectral space, and a linear map characterizing a linear transformation from the full spectral space to the Interim Connection Space.
