Title:

    Manipulating volumetric abstractions to match color perception between dissimilar gamuts

Presenter(s)/Author(s):



Abstract:


    The disparity in realizable colors of motion picture film prints and digital display devices such as CRT monitors, or digital projectors, often necessitates significant technical color correction (called grading or timing) prior to arriving at a master negative suitable for release-print duplication. This gamut mismatch is often exaggerated in computer-generated content, where the palette is not inherently constrained by original camera negative and more readily exercises colors beyond the gamut of release print film stocks.
    We present a novel interactive technique called Synthetic Grading which leverages GPU acceleration, designed to efficiently refine procedurally generated color transformations to attain a perceptually accurate match between devices of significantly disparate gamuts.
