很经典的一款统计器,可以分时期统计访问量。(Statistics is a classic, you can sub-period traffic statistics.)

图像分割的方法有许多种，其中阈值分割的方法很常用，提供一种基于otsu算法的图像分割方法，很实用。(There are many kinds of method of image segmentation, threshold segmentation method is commonly used, provide a method of image segmentation based on otsu algorithm is very practical)

求解时滞微分方程组，并给出了Matlab程序的源代码(Delay Differential Equation, and gives the the Matlab program source code)

调试成功的测距定位仿真（TOA）。三个函数的作用分别是：在一个正方形区域内随机选择10个点；在这10个点中选择被测结点和参考结点；LSE位置计算。(Ranging and Location debug successful simulation (TOA). The role of the three functions are: a square area in 10 randomly selected points 10 points in the selected node under test and reference nodes LSE position calculation.)

说明：  作为具有高分辨以及成像功能的合成孔径雷达，已广泛被各国所研究。而RD算法却是成像领域最基础最最熟的基础算法。在此提供各大家，共同研究！(As well as a high-resolution synthetic aperture radar imaging, has been widely studied by various countries. The RD algorithm is most familiar image of the most basic of basic algorithms. Here are the people, to study!)

说明：  里面有一篇非局部均值去噪的文章，并附有代码。经调试，代码正确。(There are a non-local means denoising article, along with the code. After debugging, the code is correct.)

SAR数据，经典Freeman-Durden极化分解程序，(SAR data, a classical Freeman-Duren decomposition procedure, helps better understand polarimetric decompositionenhancement, etc.)

一种新的基于matlab环境的用SVD原理实现图像压缩的源程序，程序简单易懂(Implementation of new image compression using SVD, the program easy to understand)

同轴线的计算，内有注释说明同轴线的计算，内有注释说明(Coaxial line calculation, there are comments that the calculation of coaxial line, there are explanatory notes)

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)
