In this study, a functional colorant, Berberine, extracted from Berberis vulgaris wood was applied onto wool fiber using the extract of roots of Rumex Hymenosepolus as biomordant. The effect of treatment variables on the color strength of dyed fibers was examined. The fastness properties of dyed wool against washing, light, dry and wet rubbing were evaluated. Dyed samples were tested for an...

Nowadays, because of the growing numbers of vehicles on streets and roads, the use of intelligent controlsystems to improve driving safety and health has become a necessity. To design and implement suchcontrol systems, having information about traffic light colors is essential. There are the wide variety oftraffic lights in terms of light intensity and color. Therefore it seems that design and ...

In this paper, a new technique for color reproduction based on color variation characteristics of digital camera under a dim light condition is proposed. Generally, photographers should adjust a camera exposure properly for obtaining an image with real color tone of subjects. Thus, in case of taking a picture under a dim light condition, the exposure time of a camera has to be relatively longer...

Light and color are ubiquitous environmental factors which have an influence on the human being. Hence, light and color issues have to be considered especially significant in human-computer interaction (HCI) and fundamental in affective computing. Affective computing is an interdisciplinary research field which aims to integrate issues dealing with emotions and computers. As a consequence, it s...

An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...

Galaxies are lighthouses that sit atop peaks in the density field. There is good observational evidence that these lighthouses do not provide a uniform description of the distribution of dark matter.

Rod influence on hue appearance of spectral lights was characterized by comparing the scaling of red, green, yellow, and blue hue sensations for an 8 degrees-diameter, 7 degrees-eccentric test spot under conditions that minimized (cone plateau) and maximized (dark adapted) rod influence at two mesopic light levels (1.5 and 3.0 log scoptic trolands). At the lower light level, the hue-scaling fun...

PIC 18F series microcontroller is used for control of signals to a specific time using port lines. In this contest we choose the Bicolor LEDs with Red and Green. The colors of the signals are illuminated by programming in the microcontroller. The aim of this paper is to generate three colors on a single traffic light instead of using three different color traffic signal lights. The purpose of t...

Computational color constancy aims to estimate the color of the light source. The performance of many vision tasks, such as object detection and scene understanding, may benefit from color constancy by using the corrected object colors. Since traditional color constancy methods are based on specific assumptions, none of those methods can be used as a universal predictor. Further, shallow learni...
