Spectral basis representations

For large spectral files, we generally use linear models to represent the spectral information. That is because even though the spectral curves may be sampled at many wavelengths, the data are typically very closely modeled by a small number of basis functions. In the case of natural scenes, there has been a great deal of work characterizing the dimensionality of the illumination and surfaces.

This page will describe the sceneFromBasis and related functions. How do we store the data using a basis representation.

How do calculate the linear model basis functions for a specific scene.
