These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

When the elliptical coaxial line becomes a circular coaxial line, the mode eigenequation of the circular coaxial line can be obtained from the mode eigenequation of the elliptical coaxial line using the asymptotic formulae of angular and radial Mathieu functions.

研究表明：当椭圆退化为圆时，利用角向和径向马修函数的渐进关系，可得到填充多层介质的圆形同轴线的模式特征方程，由此可见，圆形同轴线可看作椭圆形同轴线的特例；当椭圆同轴线内导体半长轴大小为零时，则椭圆同轴线就变成椭圆波导，同样的方法，可得到填充多层介质的椭圆波导模式特征方程。

Using SUSAN formed SIFT and ladder-image pyramid structure to achieve the same scale,new algorithm establish a unified set of over-determined equations of all match points.The over-determined linear equations coefficient matrix can be simplified to drop dimension,so simplify the structure of the augmented matrix and whose dimension is reduced to half.

本文对对应分析法在分类中作了改进，提出向量夹角分角线的客观分类判据，并把这一方法应用到北京冬季气温分类上，结果表明它比其它分类法更直观、提取信息量更多，能较好地反映天气过程本质。

In order to resolve the conflict between excessive data storage, time expensive computation and real-time image processing, a method is proposed based on distance transfer with chamfer to extract the position and scale features of each objects, then a five points square predictor is used to estimate the position of objects next time and compute the velocity. Finally, objects are associated using improved weighed nearest neighbor. The algorithm is implemented on the platform of Xilinx XCV300E+ADI Blackfin 532 DSP.

为了解决多目标跟踪中数据存储量、运算量大与实时处理之间的矛盾，提出了一种基于倒角算子距离变换的多目标分离方法，分别提取出各个目标的位置和大小信息，再采用五点二次预测估计出下一场目标的位置从而得到目标的运动速度，最后由改进的加权最近邻算法进行目标特征关联。

Introducing the Darwin's method of treating x-ray diffraction in crystals into Bragg diffraction for multilayer structure, a series of analytical expressions are obtained, which can be used to calculate the reflectivity, the Darwin's width, the minimum number of periods and the energy resolution.
