datasets

eyes

Calculate with spectral properties of light sources, materials, cameras, eyes, and scanners.
Build complex systems from simpler parts using a spectral product algebra. For light sources,
compute CCT, CRI, and SSI.  For object colors, compute optimal colors and Logvinenko coordinates.
Work with the standard CIE illuminants and color matching functions, and read spectra from
text files, including CGATS files.  Estimate a spectrum from its response. A user guide and 9 vignettes are included.
