Color Difference Evaluation Model on Partly Changed Complex Images
Since there has been a strong demand from industry to have an efficient way of managing color image quality presented in different media, by specifically investigating partly changed complex images, this article proposed a revision to existing CIE color difference model which cannot give a proper color difference assessment on partly changed complex images. The key method applied is to find out...
متن کاملConstructing 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 کاملColor Appearance and Color Difference Specification
116(Y/Yn)^1/3-16. The exponent 1/3 is omitted in the published text. In addition, the leading factor in the expression for b* should be 200 rather than 500. 3) In the expression for "deltaH*_94" just above Eq. 5.8, each term inside the radical should be squared.
متن کاملUpgrading color-difference formulas.
We propose a method to improve the prediction performance of existing color-difference formulas with additional visual data. The formula is treated as the mean function of a Gaussian process, which is trained with experimentally determined color-discrimination data. Color-difference predictions are calculated using Gaussian process regression (GPR) considering the uncertainty of the visual data...
