Investigating Euclidean Mappings for CIEDE2000 Color Difference Formula

چکیده
In recent years, various color difference formulas were developed for the CIELAB space, such as CMC, CIE94 and CIEDE2000. Although these formulas have achieved greater accuracy in perceptual measurement between colors, many applications cannot take advantage of this greater precision, because the Euclidean distances in CIELAB are not isometric in accordance with these new formulas. Thus, applications such as gamut mapping and color interpolation need a color space that is isometric in relation to the latest color difference formulas. This paper studies the mapping of the CIELAB space, particularly the ab plane of this space according to the metrics of the CIEDE2000 formula, through multidimensional scaling (MDS) techniques, more specifically ISOMAP and an optimization based on Sammon Mapping.

Constructing Euclidean Color Spaces based on Color Difference Formulas
This paper shows a computational technique of how to construct a nearly isometric transformation from a color space with a non-Euclidean color difference formula into an Euclidean space. The resulting transformation is a combination of a one-dimensional color lookup table (CLUT) to transform lightness values and a two-dimensional CLUT to transform chroma and hue coordinates. As an example the C...
متن کاملRiemannian Formulation of the CIEDE2000 Color Difference Formula
The CIELAB based CIEDE2000 colour difference formula to measure small to medium colour differences is the latest standard formula of today which incorporates different corrections for the non uniformity of CIELAB space. It also takes account of parametric factors. In this paper, we present a mathematical formulation of the CIEDE2000 by the line element to derive a Riemannian metric tensor in a ...
متن کاملHow Perceptually Uniform Can a Hue Linear Color Space Be?
We propose a numerical method to determine a transformation of a color space into a hue linear color space with a maximum degree of perceptual uniformity. In a first step, a transformation of the initial color space into a nearly perceptually uniform space is computed using multigrid optimization. In a second step, a hue correction is applied to the resulting color space while preserving the pe...
متن کاملGeneralized industrial color-difference space based on multi-stage color vision and line-element integration
A generalized color-difference space was introduced based on theories of multi-stage color vision, for example, the zone theory, and extended by integrating line elements. This space had the following features: chromatic adaptation, a linear transformation from CIE tristimulus values to cone fundamentals, a nonlinear compression stage, a second linear transformation to opponent signals, and lin...
متن کاملPerformance of a color-difference formula based on OSA-UCS space using small-medium color differences.
An investigation of the color metrics and the complexity of the CIEDE2000 formula shows that CIELAB space is inadequate to represent small-medium color differences. The OSA-UCS (Uniform Color Space) Committee has shown that no space with uniform scale for large color differences exists. Therefore the practical way for color-difference specification is a color-difference formula in a nonuniform ...
