摘要：

We propose a new geometric method to compute color gamut boundaries fast and geometrically accurate. The method is designed for high-quality image-dependent gamut mapping in three dimensions. For such a mapping the gamut boundary must be constructed for every image individually and we cannot rely on precomputed lookup tables. This can only be practical if the gamut boundary can be computed very fast. The proposed method is fast compared to other geometric methods without sacrificing geometric accuracy of the computed boundary.
