合成孔径雷达（SAR）回波模拟半实物仿真平台的构建(Synthetic aperture radar (SAR) analog echo-loop Simulation Platform)

图像拼接算法中尺度不变特征转换（sift）源码。经过本人测试修改完全可用，对matlab还不怎么熟练的新手有很大帮助。(Image mosaic algorithm scale invariant feature transform (sift) source. After I test change is totally available, not on how skilled novice matlab great help.)

利用匹配滤波器实现图形识别，包括程序和说明文档(Graphic Recognition Using Matched Filter)

一个很好类子来说明类模板的使用，可以比较明了类模板的使用方法，最好进行单步调试(use of class template )

此程序用于画混沌系统的相图及其分叉图，使用时只需要写出相应的混沌微分方程，便可画出相应的图(This procedure for drawing the phase diagram of chaotic systems and its Poincare section, when used only need to write the corresponding chaotic differential equations, will be able to draw the corresponding graph.)

本代码实现的功能：24位位图（BMP）的灰度化。具体实现过程：打开图像文件,找到数据区(每3个字节代表一个象素的R,G,B值),循环扫描,根据RGB的权重,计算出灰度值. 如果要得到256色灰度图,则要新建一个调色板,修改信息头和文件头.(Realize the function of the code: 24-bit bitmap (BMP) of the gray. Concrete realization of the process: Open the image file, locate the data area (3 bytes per pixel on behalf of a R, G, B values), cyclic scan, according to the weight of RGB, gray value is calculated. If you want to get 256 colors grayscale, would create a new palette, modify the header and file header information.)

thin plate spline（薄板样条）模型，将已知图像通过非刚性变换得到所需要的图像，在图像配准中非常有用。(thin plate spline (thin plate spline) model, will be known through non-rigid image transformation to be necessary by the images of image registration in very useful.)

如题，matlab手写数字测试图像处理 样本（30+50个）加全代码加测试结果(Like title, matlab handwritten digital test image processing samples (30 + 50) plus full code plus test results)

梯度下降法的图形表示，里面有详细的中文注释，运行即可看到结果。(Gradient descent graphical representation, which the Chinese have detailed notes, you can see the results running.)

四叉树分解算法对ＲＧＢ彩色图像进行分割，ＭＡＴＬＡＢ代码，包括实验图片(Quad-tree decomposition algorithm RGB color image segmentation, MATLAB code, including test images)
