Anthocyanins are natural dye substances that provide attractive colors from red to blue. However, large quantities of Anthocyanins have been found in wastewater from soaked black beans, resulting in environmental pollution. The utilization of theses wastewaters would therefore be an effective way of reducing environmental pollution, and the water could be used to dye silk fabric, displaying...

In the style of binary shading, shape and illumination are depicted using two colors, typically black and white, that form coherent lines and regions in the image. We formulate the problem of assigning colors in the rendered image as an energy minimization, computed using graph cut on the image grid. The terms of this energy come from two sources: appearance (shading) and geometry (depth and cu...

Color dropout refers to the process of converting color form documents to black and white by removing the colors that are part of the blank form and maintaining only the information entered in the form. In this paper, no prior knowledge of the form type is assumed. Color dropout is performed by associating darker non-dropout colors with information that is entered in the form and needs to be pr...

Let G be a graph with a threshold function θ : V (G) → N such that 1 ≤ θ(v) ≤ dG(v) for every vertex v of G, where dG(v) is the degree of v in G. Suppose we are given a target set S ⊆ V (G). The paper considers the following repetitive process on G. At time step 0 the vertices of S are colored black and the other vertices are colored white. After that, at each time step t > 0, the colors of whi...

This study proposes a novel analysis system for printed fabrics that can automatically make color separation and identify repeat patterns. The system uses a scanner to obtain red, green and blue (RGB) color images of printed fabrics and then convert them into hue, saturation, intensity (HSI) color images. In order to obtain color separation, a genetic algorithm is used to search for a smaller s...

To investigate whether ocular albinism type 1 (OA1) is differentially expressed in the skin of mice with different coat colors and to determine its correlation with coat color establishment in mouse, the expression patterns and tissue distribution characterization of OA1 in the skin of mice with different coat colors were qualitatively and quantitatively analyzed by real-time quantitative PCR (...

We show in Fig. 1 and Fig. 2 the output of our HFL algorithm on 16 examples of the YUD database using edges extracted trough Tardif’s detector [3] (two different examples are shown in [1]). The colors red, green and blue correspond to the directions of the Manhattan frame, while the other colors e.g. magenta, cyan, yellow, indicate non-orthogonal VPs. The edges marked in black received the empt...

In this study children's emotional associations with colors were investigated. Sixty children (30 girls, 30 boys), equally divided into groups of 5-year-olds and 6 1/2-year-olds, were asked their favorite color and were then shown nine different colors, one at a time and in a random order. For each color, children were asked, "How does (the color) make you feel?" All children were able to verba...
