A Discussion on Printing Color Difference Tolerance by CIEDE2000 Color Difference Formula
Applied Mechanics and Materials, 2012In ISO printing standards, a color difference tolerance of ΔE*ab=5 is used as a threshold. But CIELAB color space is not uniform enough so that the same color difference value represents different color difference sensation in different color area. It is proved that the color difference calculated by CIEDE2000 is closer to the human sensation, so ISO ...

Visual and instrumental shade matching using CIELAB and CIEDE2000 color difference formulas
Dental Materials, 2016To compare visual and instrumental shade matching performances using two shade guides and three color difference formulas.One hundred dental students (DS) volunteers (35 males and 65 females) with normal color vision participated in the study. The spectral reflectance of 4 extracted human upper central incisors (UCI) and shade tabs from Vita Classical (

SUMMARY The purpose of this study was to evaluate the ability of three resin composite systems to mask a severely discolored background by the application of a layering technique through CIELAB and CIEDE2000 analysis. Ninety 1.5-mm-thick disc specimens were produced from three different resin composite restoration systems: IPS Empress ...

Perceptually optimized color image watermarking scheme based on CIEDE2000 color difference equation
Proceedings of 2004 International Symposium on Intelligent Multimedia, Video and Speech Processing, 2004., 2005In this paper, a wavelet-based color image watermarking scheme is proposed, which is perceptually optimized by a visual model based on the CIEDE2000 color difference equation. The visual model estimates the distortion visibility threshold (DVT) for each wavelet coefficient of each color channel.

Derivation of a hue-angle dependent, hue-difference weighting function for CIEDE2000
SPIE Proceedings, 2002CIE technical committee TCl-47 was established with a goal to improve the performance of the CIE94 color-difference equation. Recent visual experiments indicated that a hue-angle dependency might exist. Four datsets focused on hue differences were used to derive a new hue-angle function.

A method to quantify the ornamental value (OV) of a flower of garden rose (Rosa Ahybrida) was created, based strictly on measurements. Here OV means the capacity to produce a uniform colour effect. The blooming time of flowers was distributed into 23 phenological sub-stages from the immature bud to the falling of petals.
