Hue Correction LUTS - Gustav Braun

Lookup tables for transforming CIELAB to and from Hung and Berns hue-corrected space

This information pertains to Appendix H of the Ph.D. dissertation A Paradigm for Color Gamut Mapping of Pictorial Images, by Gustav J. Braun, RIT, 1999. These look up tables were used to transform to and from the Hung and Berns hue corrected space (see P.Hung and R.Berns, "Determination of Constant Hue Loci for a CRT Gamut and Their Predictions Using Color Appearance Spaces," Color Res Appl 20, 285-295, 1995.)

The LUTs are stored in plain text, tab-delimited ASCII files. The file forwardLUT.txt contains the LUT that transforms CIELAB hue to the Hung and Berns corrected hue. The file inverseLUT.txt contains the LUT that transforms Hung and Berns corrected hue to CIELAB hue. The data from these files can be used to estimate the destination hue for any given input color, specified by its [Cab*,hab] coordinates, using bilinear interpolation.
