Vulnerability to occlusion is one of the main issue in visual tracking. In this proposal, we exploit the local grid features to build a robust tracker. To improve performance under occlusion, local and global features are modeled for a target tracking. Cooperating with the novel features, a new segmentation and similarity measurement are proposed for exploring the local grid advantages. Experimental results show that our tracker outperforms other two effective visual tracking methods under occlusion.

The configuration matrix obtained through the global radial basis function collocation method is usually an asymmetry full matrix and highly ill-conditioned for parabolic equations. To overcome the deficiencies, a radial basis meshless domain decomposition algorithm is proposed. It has the advantages of both the radial basis collocation method and the domain decomposition method. The new method can transform the solution to a large-scale problem into the solutions to several small sub-area ones. It effectively reduce the condition numbers of the collocation matrix. It is shown by numerical example that this method improves the stability and accelerates convergence of the numerical solution to parabolic equations.

In this paper we present a method for constructing a control model of loading systems based on higher order singular decomposition (HOSVD) of a tensor. Modern logistics need control systems that are able to develop and improve the material and information flow by automating the control processes. We propose the application of linear parameter varying (LPV) structure by which non-linear systems can be controlled on the basis of linear control theories. Describing the system, modeling logistic processes require many uncertain input parameters. Using the proposed method the complexity of the model can be kept on a lower level.

In order to solve cost-effectively the scaling problems of pipelines in oil and gas gathering system, on the basis of analyzing the application, mechanism, influence factors of electromagnetic Dirt-remover &Dirt-proof (EDD), we designed a set of reliable and practical experiment system. This system uses the microcontroller as the main controller, which containes bridge type circuit, LED circuit and various sensors. It produces a kind of current, the polarity, amplitude and frequency of which changed rapidly to contribute to produce magnetic field rapidly changed in pipeline, which changes water molecules and water ion characteristics to achieve the purpose of anti-scaling &dirt-remover. We simulated circulating water system and tested the effect of the EDD device in the field. The experimental results indicate the EDD can restrain scaling on a certain extent and have a better anti-scaling effect.

Model transformation is to construct a computable automaton to over-approximate the original automaton. In this paper, the linear phase-portrait approximation is extended to the polynomial phase-portrait approximation, and the construction process of polynomial phase-portrait approximation is presented. To refine the coarse abstract model, the model can be gradually refined by increasing the order of polynomials or restricting errors. Finally, the effects of the two refinement approaches are compared by simulation.

This paper presents an efficient algorithm on video shot segmentation of the adaptive threshold. First of all, the features of the images color and texture will be extracted by using the wavelet transform, then the mutation and gradual shot boundary detection will be achieved by utilizing the information entropy. According to the difference distribution of the sliding window, the local threshold will be calculated dynamically. And the degree of accuracy on the video shot segmentation algorithm is increased. This method can not only detect the mutation shots but also the gradual shots. The experimental results show that this algorithm method can efficiently deal with the video shot segmentation.

To deal with information security problem, an effective information hiding technique on the motivation of frequency hopping and 2D-DWT is proposed in this paper. By means of frequency hopping technique, images for hiding information are changed randomly as the time sequence of information bits according to the secret key by which randomicity and security can be improved. Experimental results show that the system on the basis of this technique is effect on hiding multiple information bits in different image without suspicion and the information can be safely extracted even if the images are subjected to normal image processing or malicious attacks.

Most of speech enhancement systems suffer from annoying musical residual noise which significantly reduces the perception quality of enhanced speech. In this study, we aim at reducing the musical residual noise by a two-stage speech enhancement approach. At the first stage, a noisy speech signal is enhanced by a three-step speech enhancement system which is constituted of two-step noise reduction algorithm and Virag method. Hence the enhanced speech signal is post-processed by a directional-median filter to significantly reduce the amount of residual noise, while the harmonic spectra can be well maintained at an acceptable level. Experimental results show that the proposed approach can significantly improve the performance of a speech enhancement system by reducing the quantity of residual noise.
