Color Identification on Heterogeneous Bean Landrace Seeds Using Gaussian Mixture Models in CIE L*a*b* Color Space

Mathematical and Computational Applications
The classification of bean landraces based on their coloration is of particular interest, as the color of these plants is associated with the nutritional components present in their seeds.

A Novel Method of Color Appearance Simulation Using Achromatic Point Locus With Lightness Dependence

i-Perception, 2018
The purpose of the present study is to propose a simple algorithm for color appearance simulation under a color illuminant. Achromatic point is a chromaticity of rays that appear neither red nor green, neither blue nor yellow under a given illuminant ...

Effects of Dehulling and Extrusion‐Cooking on the Nutritional and Physicochemical Properties of Navy Bean (Phaseolus vulgaris L.) Flours

ChemFoodChem, EarlyView.
Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...

Sistema CIE Lab: análise computacional de fotografias

, 2014
For years, the methods of choice of color in dentistry, have been made subjectively, based on individual clinical experience, without any scientific basis. With the increase in esthetic restorations, the most sought in recent decades, for better color choice are the visualand instrumental techniques.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.
