基于点云的谷脊线特征提取算法研究：提出一种基于多步逼近策略的点云特征提取算法(Exaction of ringle and ravine.)

说明：  一个基于样例的图像修补技术的matlab演示(A sample-based image repair technology demo matlab)

在matlab中实现透视变换。算法正确高效，这种仿射变换经过修改后可用于图像矫正或者摄像机标定等用途。(Matlab in perspective transformation. Correct and efficient algorithm modified this affine transformation can be used to image correction or camera calibration purposes.)

解决一些图像处理的小问题，具体的划分和问题，文件里有提到(Solve some small problems in image processing)

利用opencv库写的一个关于图像孔洞填补的小程序，附加了效果图片(Using the opencv library to write a small program on the filling of the hole, the additional effect of the picture)

K-Means算法,不要求建立模型之后对结果进行新的预测，没有相应的标签，只是根据数据的特征对数据进行聚类。主成分分析降维对数据进行可视化操作,对features进行降维.(K-Means algorithm does not require the establishment of the model after the new prediction of the results, there is no corresponding tag, but only on the characteristics of data clustering data. The principal component analysis reduces the dimension, carries on the visualization operation to the data, reduces the dimension to the features.)

基于均值漂移的图像平滑MATLAB源戴码。(Based on mean-shift image smoothing Dai MATLAB source code.)

雷达成像技术中的ISAR包络对齐Mathlab原码(original code of profile aligning for ISAR motion compensation)

中值滤波，取出奇数个数据进行排序，用排序后的中值取代要处理的数据即可(median filtering.rar)

MATLAB图像处理程序，批量将彩色图片转换成灰色图像，用于其他图像处理程序(MATLAB image processing, batch convert color pictures of the gray image used for other image processing program)
