Texture synthesis is widely recognized to be important for computer graphics applications. However, the traditional texture synthesis algorithm based on ω-tile did not provide the quantitative analysis of all sets of ω-tiles. In this paper, all possible sets of 4, 8 and 16 ω-tiles that meet certain criteria are presented firstly. Secondly, a novel evaluation system is proposed to measure the quality...
Substation grounding system is to ensure the power system operation safe and reliable. It is important to examine the state of grounding. In this paper, optimization algorithm is used for grounding grid fault diagnosis. The method that used combination of rotating and encouraging each location and incentives, many measurements, utilized the fact that the corrosion resistances must be increased, established...
We present a detailed description of an algorithm to detect the Mid-sagittal Line (MSL) in the human brain CT. The method seeks the line with respect to the image maximum symmetry. Our method relies on the moving window to define the counterpart points between both sides of the brain with the symmetry line. The matching points are measured by the adaptive weighted mutual information based on local...
In this article, the author designs a Parrondo's game model of biotic population with the BA scale-free network as its spatial carrier, trying to analyze the individual's competitive and cooperative behaviour. The populational Parrondo's game model includes zero-sum games among individuals and the negative sum-up games between individuals and environment. In terms of zero-sum game relations, four...
Due to the particular tubular molecular structure, carbon nanotubes exhibit various excellent physical and chemical properties and potential application prospect. With constantly developing preparation technology of carbon nanotubes, decoration and application of carbon nanotubes arouse widespread attention. Carbon nanotubes coated with TiO2 and ZnO nanoparticles (TiO2-CNTs and ZnO-CNTs) were performed...
An extended method for obtaining crypto-graphically strong substitution boxes (S-boxes) based on discretized chaotic map system (DCMS) is presented in this paper. The S-boxes' design criteria such as bijection, nonlinearity, strict avalanche, output bits independence and equiprobable input/output XOR distribution of these S-boxes are analyzed in detail. The results of numerical analysis show that...
