Color images are usually viewed on CRT monitor screen under ambient light sources. The feeling for reproduced color on CRT monitor depends on white point of ambient light source and the CRT monitor screen'-3. Therefore, if the effect of ambient light source is not considered, then the reproduced color does not match the intrinsic color. This paper proposes a method to investigate the effect of ...

The use of metamerism index & color inconstancy index is studied for approval of spot colors used in decorative gravure products, especially spot colors, which are viewed under different light sources at the customer’s end. This work shows that the metamerism index is not sufficient for approval of spot colors, because it doesn’t provide any idea about how colors will transform under different ...

This reserch proposes a method to provide an appropriate illuminance and color temperature in an office lighting environment for individual workers. For the control algorithm, based on the optimization method called Simulated Annealing (SA), a method including a neighborhood design mechanism for the design variables instead of a temperature parameter was used. In addition, for changes in the lu...

In underwater image capturing, color change and presence of haze are the two sources of distortion. These distortions are caused by light scattering and light attenuation occurred by light traveling in water with different wavelengths. These changes are caused by light incident on objects, reflected and deflected by different particles present in the propagation path before reaching the camera....

When a speaker says the name of a color, the color they picture is not necessarily the same as the listener imagines. Color is a grounded semantic task, but that grounding is not a single value as the most recent works on color-generation do. Rather proper understanding of color language requires the capacity to map a sequence of words is to a distribution in color space. To achieve this, we pr...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Silk fabrics dyed using natural mordants: powder of sour pomegranate and sweet pomegranate and mixture them. A beautiful red color were obtained by using theses mordants. The color of dyed silk fabrics was investigated in CIE Lab L, a and b and K/S values. Finally, all dyed fabrics were tested for was...

The effects of sample thickness (0.5, 1.0, and 1.5 cm), background color (white, pink, green, and gray), and illuminant (D-65, A, and F) on color measurement of broiler tissue were determined. Color values from the anterior portions of the two Pectoralis superficialis muscles were not different from each other, allowing one to be used as a control for the other. Light penetrated the thinner pos...
