说明：  利用MATLAB对图像进行文件夹中图片进行批量增广(MATLAB is used to enlarge the images in the folder)

理解频域处理与空间域处理的等效关系与步骤，掌握频域相乘与空间域循环卷积之间的对等关系，理解DFT运算中补零的效果。(Understand the equivalent relationship and steps of frequency domain processing and space domain processing, understand the reciprocal relationship between frequency domain multiplication and space domain circular convolution, and understand the effect of zero padding in DFT operation.)

说明：  基于邻域的比例算法求两幅图像的差异图，用于变化检测。(The proportion of neighborhood-based algorithms to find the difference of the two images map for change detection.)

给定一副图像，采用一定的策略对其进行搜索以确定其中是否含有人脸，如果是则返回一脸的位置、大小和姿态(人脸检测)

用于求解张正友相机标定过程中的单应性矩阵(Homography matrix for camera calibration)

仿射投影符号算法是仿射投影算法和符号算法的组合算法，具有良好的抗冲击噪声的能力。(Affine projection algorithm is a combination algorithm symbol affine projection algorithms and symbolic algorithms, have good impact noise capabilities.)

利用libsvm对遥感影像进行分类，需在已经编译了libsvm的环境进行(Using libsvm to classify remote sensing images)

处理图像，利用提出高频的方法，把图像中的裂纹提取出来。能比较好的把背景图像和裂纹分割开来。(Processing images, the use of the proposed high-frequency method of the cracks in the image extracted. Good background image and crack separated.)

这个是用matlab编写的读取遥感图像envi的程序(This is prepared using matlab to read the procedures for remote sensing image envi)

将matlab处理得到的三维矩阵转化为envi软件可读取的数据格式raw(change the 3-D data from matlab to the raw form ENVI can read)
