By applying the comparison theorem and some new analysis technique, some sufficient conditions which guarantee the permanence of the system are obtained. After that, by constructing a suitable Lyapunov function, sufficient conditions which ensure the global attractivity of the system are obtained.

利用差分方程的有关理论，使用与前面不同的分析方法，获得保证该系统永久持续生存的充分性条件；其后通过构造适当的差分Lyapunov函数，得到保证该系统全局吸引的充分性条件。

The confidence of each region of target image is calculated according to its discriminative power between the tracking target and local background, and the target and candidate models are characterized by LBP feature probability density function weighted by region confidence and distance.

根据目标各区域对背景的区分能力不同，提出了目标各区域置信度的评价方法，用基于区域置信度及空间距离核加权的LBP特征概率密度函数，构造了目标及候选目标的特征模型。

通过在不同空间上构造委员会的偏好结构，指出了这种偏好的锥诱导性和这种偏好的有效选择与多目标决策问题的M－解之间的等价性。

Firstly, we constructed Red-Black Wavelet by Lifting Scheme. Secondly, we applied the Red-Black wavelet to two image fusion experiments: fusion of multifocus images; fusion of CCD and IR images. Finally, we evaluated the method's performance by some objective criteria based on statistics or informatics.

首先基于提升框架的思想构造Red-Black小波，然后将其应用于两组图像融合实验：不同聚焦点图像融合与可见光－红外图像融合；并分别采用基于统计特性和信息量的评价指标，将本文方法与db4张量积小波的图像融合方法进行了比较。

Based on the properties of associated surfaces for complete bipartite graphs,a new type of graph J with weak symmetry is constructed.At the same time,the minimum genus of it is derived.Finally,the number of genus embeddings of complete bipartite graphs is easily estimated.
