In assigning the weights of the first plurality of nodes, a first generation of combinations of possible weights assignable as the weights of the first plurality of nodes is obtained, and a second generation of combinations of possible weights assignable as the weights of the first plurality of nodes is obtained by performing the genetic algorithms in the first generation of combinations of possible weights. The device determines whether the document is in a document class based at least the weights of the first plurality of nodes.

Abstract: A color constancy method and system include dividing an image into a plurality of sub-images and applying a plurality of color constancy algorithms to each of the sub-images. The outputs of each of the color constancy algorithms are analyzed for each of the sub-images to determine which of the color constancy algorithms give inconsistent results across the sub-images. The influence of the outputs of the algorithms providing inconsistent results is adjusted to decrease their influence (e.g. effect or weight) with respect to the outputs of algorithms providing consistent results. The outputs from the plurality of color constancy algorithms are combined based upon the adjustment of the outputs.

Abstract: The present invention relates to a nanostructured metal powder and a method of fabricating the same. A twin-wire electric arc process is performed to melt the wire tips, and metal melt is formed. Simultaneously, the metal melt is broken up into melt droplets by an atomizing device. The operating temperature of the electric arc process is controlled between melting point and boiling point of the wire, to avoid vaporization of the melt droplets. Then, a fast cooling is performed to quench the melt droplets. Thus, melt droplets are solidified to ?m-scaled, spherical and dense powders comprising nano-grains (d<100 nm).
