The coronary angiography image is easy to be affected by many factors, such as vascular thickness varied huge, complex background noise, uneven illumination intensity and so on. The coronary angiography image is more difficult to deal with compared with other similar medical images. By using Hessian matrix multi-scale vascular detection method, the vicinity(More)
In the asymmetric unit of the title compound, [Ag(C(10)H(6)N(4))(2)(CF(3)CO(2))], there two mononuclear but slightly different complex units. In each, two κ(2)N:N-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, giving an N(4)O square-pyramidal coordination geometry with one trifluoro-acetate O atom at the apex. The(More)
