All sophisticated methods for direct determination of methanol require advanced instruments and high technical knowledge which preparing them is very expensive in none developed and developing countries. This work reports a simple and efficient qualitative technique for semi determination of methanol content in herbal distillates by a new modified chromotropic acid method. The technique is base...

In order to identify the perceived qualities of texture and color in a building mathematical models for object a optimized and efficient algorithm ‘A Fast HSV Image Color and Texture Detection Algorithm’ based on color intensity using Artificial Intelligence and fuzzy Logic is presented in this paper. We will be using color intensity method over conventional method. The ‘Fast HSV Image Color an...

A comprehensive solution set of strategies is proposed for interior color design in this study. Computer aided design methods are utilized to solve the problems in the color scheme process, the existing circumstances, shortage and trend of current color scheme tools are analyzed based on interior design theory and modern design methodology. The appropriative color space is constructd to redound...

This study explores how the lack of first-hand experience with color, as a result of congenital blindness, affects implicit judgments about "higher-order" concepts, such as "fruits and vegetables" (FV), but not others, such as "household items" (HHI). We demonstrate how the differential diagnosticity of color across our test categories interacts with visual experience to produce, in effect, a c...

The ability of observers to make reliable judgments of surface color despite changes in an illuminant (“color constancy”) has sometimes been attributed to their estimating the spectral properties of the illuminant in order to discount its effects. To test how information about the illuminant contributes to surface-color judgments, observers’ performance in two surface-color-matching experiments...

A color algebra refers to a system for computing sums and products of colors, analogous to additive and subtractive color mixtures. The difficulty addressed here is the fact that, because of metamerism, we cannot know with certainty the spectrum that produced a particular color solely on the basis of sensory data. Knowledge of the spectrum is not required to compute additive mixure of colors, b...

Originating in the grapes, monomeric anthocyanins in young red wines contribute the majority of color and the supposed beneficial health effects related to their consumption, and as such they are recognized as one of the most important groups of phenolic metabolites in red wines. In recent years, our increasing knowledge of the chemical complexity of the monomeric anthocyanins, their stability,...

This paper addresses the problem of lip segmentation in color space, which is a crucial issue to the success of a lip-reading system. We present a new segmentation approach to lip contour extraction by taking account of the color difference between lip and skin in color space. Firstly, we obtain a lip segment sample via a color transformation sequence in 1976 CIELAB and LUX color spaces. Second...

This paper addresses the problem of lip segmentation in color space that is a crucial issue to a successful lip-reading system. We present a new segmentation approach to lip contour extraction by taking account of the maximum a posterior Markov random field (MAPMRF) framework. We first examine various color models and select a simple color transform derived from LUX and 1976 CIELAB color space ...

In order to evaluate the effectiveness of a color-sketch retrieval system for a given multimedia database, tedious evaluations involving real users are required as users are in the center of query sketch formulation. However, without any prior knowledge about the bottlenecks of the underlying sketch-based retrieval model, the evaluations may focus on wrong settings and thus miss the desired eff...
