2维相控阵方向图，用的是fft算法，验证正确为。(wo-dimensional phased-array pattern, using the fft algorithm, the right to verify.)

这是本人自己实现的椭圆检测算法，基于MATLAB实现，经测试对一些图片椭圆检测效果较好，需要同学可以参考(This is my own implementation of ellipse detection algorithm based on MATLAB implementation, tested on a number of pictures ellipse detection is better, students can refer to the need to)

说明：  图像预处理，灰度化，滤波，将图像输入后经过算法得到灰度图，然后进行后续一系列转化，拟合圆和椭圆曲线(Image preprocessing, graying, filtering)

KI阈值算法，实现SAR图像变化检测时判别变化与非变化的区域所需要阈值的选取(the Kittler and Illingworth minimum-error thresholding algorithm)

给出了灰度图像（256*256大小）的三层高斯和拉普拉斯金字塔分解的程序和实现方法。内容包括：1.matlab源码，亲身实践，因为论文需要，自己专研的。完全可用。2.国外最先最权威的关于分解原理介绍的文章。以上两个内容中都有本人的悉心注释和思路总结，内容详尽。3.图示结果(code and principle of laplacian pyramid decomposition of a gray scale image are provided in the article.Contents are given in detail including the notes and usage. )

介绍了混合高斯背景建模法提取运动目标的过程，自己写的，比较好理解，付视频一个，用自己的视频也可以(Describes the process of Gaussian mixture background modeling method to extract moving target, write your own, is better understood, paid a video, you can use your own videos)

很好用的Log-Gabor变换源代码，可以用于图像的特征提取(Good use of Log-Gabor transform source code, can be used for image feature extraction)

此文档中的代码可以计算5种图像的质量参数，分别是：图像灰度均值、图像方差、图像平均梯度、熵和峰值信噪比及均方误差。(The code in this document can be calculated five kinds of image quality parameters, namely: the image gray value, image variance, average gradient image, entropy and peak signal to noise ratio and mean square error.)

用matlab语言实现图像的腐蚀和膨胀，不是用自带函数(Language with matlab image erosion and dilation, not with their own function)

说明：  matlab绘制，非线性分叉图，非线性动力学(Matlab drawing, nonlinear bifurcation diagram, nonlinear dynamics)
