Dental ceramics: A CIEDE2000 acceptability thresholds for lightness, chroma and hue differences

Journal of Dentistry, 2011
To determine the visual 50:50% acceptability thresholds for lightness, chroma and hue for dental ceramics using CIEDE2000(K(L):K(C):K(H)) formula, and to evaluate the formula performance using different parametric factors.A 30-observer panel evaluated three subsets of ceramic samples: lightness subset (|ΔL'/ΔE(00)| ≥ 0.9), chroma subset (|ΔC'/ΔE(00)| ≥

Comparison of the CIELab and CIEDE2000 color difference formulas

Journal of Prosthetic Dentistry, 2016
Many color specification systems and color differences have been proposed to improve the correlation between color measurement and visual perception. Although color differences can be quantified using either the CIELab formula (ΔE*(ab)) or the recently introduced CIEDE2000 formula (ΔE00), which captures the perceived color difference better is unknown ...

Riemannian Formulation of the CIEDE2000 Color Difference Formula

open access: yesColor and Imaging Conference, 2010
International audienceThe 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.

Applicability of CIELAB/CIEDE2000 formula in visual color assessments of metal ceramic restorations

Journal of Dentistry, 2012
To investigate the applicability of color-difference formula (CIELAB or CIEDE2000) in visual color assessments of metal-ceramic specimens in small color-difference ranges.Metal-ceramic specimens using mixture of gradient ratio porcelain powders were fabricated to create a color pool. Color differences of specimen pairs were calculated using the CIELAB (

Comparison of CIELAB ΔE* and CIEDE2000 color-differences after polymerization and thermocycling of resin composites

Dental Materials, 2005
Though instrumental technologies have been widely used for quantifying color of esthetic dental materials, the sizes for the perceptible or acceptable color-difference varied. Instead of the CIELAB DeltaE(*)(DeltaE(ab)(*)) formula, the CIEDE2000 (DeltaE(00)) formula that included weighting and parametric functions was introduced.
