Reflectance curves and CIE L* a* b* parameters to describe patina characteristics and corrosion mechanism on bronze alloys

, 2014
This research focuses on the correlation between urban and marine environments and the corrosion behaviour of three bi-component copper-tin alloys used in different historical and artistic artifacts using colorimetry. Colorimetric measurements are useful because they are non-destructive and can be done using compact instruments, which are portable ...

Cie L*A*B* Values in VITA Classical and VITA 3D Master by Two Dental Spectrophotometers

International Journal of Prosthodontics, 2023
To compare the CIE L*a*b* values of two different dental shade guides using two shade-matching spectrophotometers.SpectroShade Micro (SS) and Easyshade (ES) (VITA Zahnfabrik) were tested. One calibrated operator performed 30 measurements of each tab from three batches of the two guides, VITA Classical (VC) and VITA 3D Shade Master (VM).

Application of the CIE-L*a*b* system to characterize soil color

Eurasian Soil Science, 2016
Identification and classification of many soils are based on their color characteristics. The main soil pigments are humus providing a dark color to soil, as well as hematite αFe2O3 and other Fe(III) (hydr)oxides coloring the soil in red and yellow. The soil classification is possible only upon the quantitative color assessment, the CIE-L*a*b* system ...

Image brightness adjustment system based on ANFIS by RGB and CIE L a b

2017 IEEE International Conference on Multisensor Fusion and Integration for Intelligent Systems (MFI), 2017
This paper proposes the method to adjust brightness information by applying CIE L∗a∗b∗ color space and adaptive neuro-fuzzy inference system. The image which is already captured by vision sensor should be adjusted brightness to recognize objects in an image.
