Fast Fourier Color Constancy [PDF]
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017 We present Fast Fourier Color Constancy (FFCC), a color constancy algorithm which solves illuminant estimation by reducing it to a spatial localization task on a torus. By operating in the frequency domain, FFCC produces lower error rates than the previous state-of-the-art by 13-20% while being 250-3000 times faster.

Dyeing of Silk Fabric with Natural Wall Nut Tree Wood Dye and Its Ultraviolet Protection Properties
Journal of Natural Fibers, 2022 Maintaining color fastness and endow functionality of the fabrics dyed with natural colorants had been the major constraint of natural dye in modern textile practices. In this work, a natural dye was extracted from wall nut tree wood.

Dyeing of polyester fibers with sulfur- and nitrogen-containing anthraquinone derivatives [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2022 A series of disperse dyes, 9,10-anthraquinone containing dithiocarbamate, thiourea and triazole fragments, were prepared via consecutive refunctionalization of aminoanthraquinones in our previous studies and their structures were confirmed by the 1H ...

ECOPRINT COLOR FASTNESS RESISTANCE ON GOATSKIN MEDIA AGAINST WET RUB AND SUNLIGHT
E-Journal of Cultural Studies, 2022 Many artisans prefer to use artificial (synthetic) dyes because they are faster and easier. However, chemical substances from synthetic dye waste are harmful to the environment.

A fast algorithm for equitable coloring [PDF]
Combinatorica, 2010 An equitable \(k\)-colouring of a graph is a proper vertex colouring with \(k\) colors, in which the sizes of any two colour classes differ by at most one. It was conjectured by P. Erdős and proved by \textit{A. Hajnal} and \textit{E. Szemerédi} [Combinat. Theory Appl., Colloquia Math. Soc.

Eco-Friendly Dyeing of Viscose Rayon Fabrics Using Anthocyanin from Hibiscus sabdariffa Linn
Journal of Natural Fibers, 2022 This paper investigates the feasibility of dyeing viscose rayon fabric with an anthocyanin solution extracted from H. sabdariffa L. calyces. For eco-friendly dyeing and improvement of the natural dye’s affinity to fabrics, natural mordants instead of ...

Fast Edge Colorings with Fixed Number of Colors to Minimize Imbalance [PDF]
Journal of Graph Algorithms and Applications, 2006 Summary: We study the following optimization problem: the input is a multigraph \(G = (V, E)\) and an integer parameter \(g\). A feasible solution consists of a (not necessarily proper) coloring of E with colors \(1, 2, \cdots, g\). Denote by \(d(v, i)\) the number of edges colored \(i\) incident to \(v\). The objective is to minimize \(\sum_{v \in V} \
