This paper deals with the use of the vector levelings for coding color images, a class of morphological connected filters which suppresses details but preserves the contours of the remaining objects. If the color images are filtered by independently leveling each color component, new colors may be introduced. In order to avoid this drawback, a total order must be imposed on the color vectors. A...

The chiral parametrization of gluons in SU (3) QCD is proposed extending an approach developed earlier for SU (2) case. A color chiral field is introduced, gluons are chirally rotated, and vector component of rotated gluons is defined on condition that no new color variables appeared with the chiral field. This condition associates such a vector component with SU (3) /U (2) coset plus an U (2) ...

The main goal of this study is determination the effect of GCR (gray component replacement) levels on colorimetric characteristics of color proof. To determine the effect of GCR levels on colors of color proofs, a comparison of 2D and 3D color gamuts depending on GCR level have been performed. In addition to obtain better assessment of the effect of GCR levels on color gamut were calculate volu...

Color plays an important role in human visual attention. Therefore, high color contrasts are often used for warning or information purposes (e.g. traffic signs, warning signs in industrial areas). In this work the color contrasts are evaluated in a perceptually uniform color space to achieve a human-like color classification. The results of the color analysis are organized in several feature ma...

Color information of natural images can be considered as a highly correlated vector space. Many different color spaces have been proposed in the literature with different motivations toward modeling and analysis of this stochastic field. Recently, color transfer among different images has been under investigation. Color transferring consists of two major categories: colorizing grayscale images ...

Pure organic luminescent materials with high efficiency in the solid state are of great importance for potential applications. Unlike blending two or three dyes, getting white-light emission from a single component is hot research topic its advantages practical Although thermo/mechanochromic smart class stimuli-responsive systems, using these to manipulate luminescence spectrum achieve full-col...

We applied independent component analysis (ICA) to hyperspectral images in order to learn an efficient representation of color in natural scenes. In the spectra of single pixels, the algorithm found basis functions that had broadband spectra and basis functions that were similar to natural reflectance spectra. When applied to small image patches, the algorithm found some basis functions that we...
