In this paper, a reformative scatter difference discriminant criterion (SDDC) with fuzzy set theory is studied. The scatter difference between between-class and within-class as discriminant criterion is effective to overcome the singularity problem of the within-class scatter matrix due to small sample size problem occurred in classical Fisher discriminant… (More)
The efficient target tracking algorithm researches have become current research focus of intelligent robots. The main problems of target tracking process in mobile robot face environmental uncertainty. They are very difficult to estimate the target states, illumination change, target shape changes, complex backgrounds, and other factors and all affect the… (More)
The traditional Back Propagation (BP) has some significant disadvantages, such as training too slowly, easiness to fall into local minima, and sensitivity of the initial weights and bias. In order to overcome these shortcomings, an improved BP network that is optimized by Cuckoo Search (CS), called CSBP, is proposed in this paper. In CSBP, CS is used to… (More)
Image segmentation process for high quality visual saliency map is very dependent on the existing visual saliency metrics. It is mostly only get sketchy effect of saliency map, and roughly based visual saliency map will affect the image segmentation results. The paper had presented the randomized visual saliency detection algorithm. The randomized visual… (More)
In the crystal of the title compound, C(18)H(22)N(2)O(4)S·2H(2)O, mol-ecules are linked into a one-dimensional chain structure by C-H⋯O, N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds.
In the title mol-ecular salt, [Co(H(2)O)(6)](C(7)H(8)NO(3)S)(2), the Co(2+) cation lies on an inversion centre. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, thereby generating sheets parallel to (001).
In the title mol-ecular salt, [Mg(H(2)O)(6)](C(7)H(8)NO(3)S)(2), the Mg(2+) cation lies on an inversion centre. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, thereby generating sheets parallel to (001).
In the title compound, [Ni(CH(5)N(3)S)(2)](C(8)H(8)N(3)O(3)S(2))(2)·2H(2)O, the Ni(II) atom lies on a inversion centre and is four-coordinated by two N and two S atoms of two thio-semicarbazide ligands in an almost square-planar coordination. In the crystal structure, the molecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, N-H⋯O, N-H⋯S… (More)
