The use of optical flow fields in image sequence analysis allows to perform motion-based segmentation as well as 3-D reconstruction. Many techniques for optical flow estimation are based on some global or piecewise global smoothness assumption. Other techniques compute the flow field based only on local information. In this paper a local algorithm explicitly addressing the problem of evaluating...

Water-soluble polymers have versatile applications but they are hardly used in wet processing of cellulosic substrates (cotton, viscose, jute, etc.), particularly in dyeing. In this paper, one such water-soluble polymer, polyacrylic acid has been synthesized, characterized and applied to viscose fabric in conjunction with various types of reactive dyes, namely triazinyl, vinyl sulphone, high ex...

The present investigation deals with synthesis of new acid dyes from 4-amino-1-(4-sulfophenyl)-3-methyl-5-pyrazolone and phenol derivatives and their metal complexes (Cu (II) and Fe (II)). The phenol derivatives include 4-chlorophenol, 4-nitrophenol, 4-hydroxybenzene sulfonic acid, 2-nitrophenol-4-sulfonic acid, resorcinol and bisphenol A and bisphenol S. The newly synthesized dyes were applied...

Textile industry comprises of dry mechanical and wet chemical processing,wet chemical process comprises of bleaches, dyeing , printing, & finishing. Dyeing is art of colouration to textiles.Dye get transferred to textile during dyeing. Dyeing operation is performed by the reaction between fiber and dyes. Some dyes are water soluble and some are water insoluble. Some fiber has affinity to dye; s...

Many clinical studies have shown that the arm movement of patients with neurological injury is often slow. In this paper, the speed analysis of arm movement is presented, with the aim of evaluating the arm movement automatically using the Kinect camera. The arm movement seems simple at the first glance, but in reality it is very complex neural and biomechanical process that can be used for dete...
