Spotting Colours
Spotting an object of a chosen colour, skin for example, in an image taken under uncontrolled lighting conditions requires some form of preprocessing to convert the image colours to an illumination-independent specification. Computational colour constancy algorithms are designed specifically to accomplish this task. We process images with different colour constancy algorithms and evaluate the r...
متن کاملLaser-induced plasmonic colours on metals
Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited to large-scale industrial applications. Here we use a bottom-up approach where picosecond ...
متن کامل2-(4-Bromophenyl)quinoxaline
In the title compound, C(14)H(9)BrN(2), the benzene and quinoxaline rings are almost coplanar [r.m.s. deviation = 0.0285 (3) Å and dihedral angle = 2.1 (2)°].
متن کاملQuinoxaline-2-carbonitrile
In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H⋯N inter-actions, forming R(2...
متن کامل2-(4-Chloroanilino)quinoxaline
There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(10)ClN(3), with dihedral angles of 5.11 (10) and 13.61 (10)° between the aromatic ring systems. In the crystal structure, mol-ecules are linked by N-H⋯N hydrogen bonds, resulting in chains propagating in [010].
