Windows Detection Using K-means in CIE-Lab Color Space
2010 20th International Conference on Pattern Recognition, 2010In this paper, we present a method for window detection, robust enough to process complex facades of historical buildings. This method is able to provide results even for facades under severe perspective distortion. Our algorithm is able to detect many different window types and does not require a learning step.

Performance of CIE LAB-Based Color Difference Formulae under Different Viewing Conditions
Advanced Materials Research, 2012In order to investigate the performance of color difference formulae under different viewing conditions 144 pairs of sample around 17 color centers were designed and printed, and then assessed visually under four different viewing condition. STRESS values between the visual color difference and calculated color difference by five CIELAB-based color ...

Abstract There are several commercial sugar syrups obtained from the Mesquite pods, however their dark-brown colour limits their use in the food industry. In this work we clarified sugar syrups from Mesquite pods by a two-step procedure: (1) lime-milk treatment with the addition of different amounts of calcium hydroxide and aluminium ...

Age related tooth color changes according to CIE Lab color scale
2020Introduction: Aging is a normal biological process in which the human body is changing irreversibly. Oral tissues also are not spared from that process. In general, tooth color is a very important reason for better self-confidence at any age. Aim: The purpose of this study was to determinate how aging affects tooth color, and to show how is tooth color

Shade guides continue to be the most widely used method in clinical practice for shade selection of restorative materials. The Vitapan shade guide is the most widely used method in clinical practice for shade selection of restorative materials. The Vitapan shade guide is the universal standard against which shade matching for ceramics is done. The same

The International journal of prosthodontics, 2005
In addition to the CIE Lab color-difference formula (deltaE*ab), advanced formulas that include weighting functions have been introduced. The objectives of this study were to determine the correlations in color differences between different shade pairs of resin composites by different color formulas, and to determine whether the weighting functions ...

Relation between CIE lab color values and the lignin content of kraft pulps during bleaching
2003Residual lignin in unbleached kraft pulp and unbleached pulps from CEHDED stages correlate well with the color values of the same materials of known CIE L* a*, b*, C* and h* values. L* and C* values of pulps were evaluated to estimate their residual lignin.
