Gamut Boundary Determination using Alpha-Shapes
نویسندگان
چکیده
This paper proposes a solution to the problem of finding the boundary of the gamut of a color printing device or of a color image. A surface triangulation of a set of points in the color space is computed using an alpha-shape, which is a generalization of a convex hull applicable also to nonconvex solids. The desired level of detail can be controlled by means of an alpha parameter. A method for selecting the suitable value of this parameter is proposed.

Simplified Gamut Boundary Representation using Mesh Decimation
Gamut boundary determination is an important step in device characterisation and colour gamut mapping. Many different algorithms for the determination of colour gamuts are proposed in the literature. They vary in accuracy, computational efficiency, and complexity of the resulting triangulated gamut surface. Recently, an algorithm called uniform segment visualization (USV) was developed. The gam...
متن کاملEvaluation of Algorithms for the Determination of Color Gamut Boundaries
p d i bstract. Several techniques for the computation of gamut boundries have been presented in the past. In this article we take an n-depth look at some of the gamut boundary descriptors used when erforming today’s gamut mapping algorithms. We present a ethod for evaluating the mismatch introduced when using a decriptor to approximate the boundary of a device gamut. First, a isually verified r...
متن کاملGamut Boundary Determination by Sampling an Inverse Printer Model
In this paper we present a novel method to calculate the gamut boundary of a color printing device using a sparse number of measured values. This method belongs to the SMGBD (Segment Maxima Gamut Boundary Descriptor ) family. At first, we construct an inverse printer model based on a set of printed color patches. This model allows us to find the colorant values that have to be sent to the print...
متن کاملColor image enhancement technique using gamut mapping based on color space division
This paper proposes a gamut mapping algorithm based on color space division for color reproduction of cross media. As each color device has a limited range of producible colors, the reproduced colors on a destination device are different from those of the original device. In order to reduce the color difference between those devices, the proposed method divides the whole gamut into parabolic sh...
متن کاملToward image-dependent gamut mapping: fast and accurate gamut boundary determination
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...
