说明：  这是一个实现图像缩放的MATLAB源代码，可以有用户自己调节缩放的倍数(This is an image scaling to achieve the MATLAB source code, users can zoom in multiples of its own regulation)

说明：  利用PCA对人脸图像进行降维，然后训练神经网络分类器的Matlab程序(the Matlab in face recoginization using PCA algorithm)

说明：  计算凸包面积，点集Q的凸包是指一个最小凸多边形，满足Q中的点或者在多边形边上或者在其内。(Calculate convex hull area。The convex hull of point set Q is a minimum convex polygon, to meet the Q of the point or polygon or in its inside edge)

说明：  以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

说明：  一个较好效果的彩色图像合成代码(分左右两个视窗,点击左边的视窗后显示左图,选择操作后,点击右视窗,可看到各种不同合成操作的效果图)(a good result Color Image Synthesis code (around two windows, Click on the left side of the window shows the municipality, the choice of operation, click on the right window we can see various synthesis operating results))

Algorithm for drawing elipse

说明：  VC做的图像直方图均衡化小程序，有助于学习图像处理基本知识(VC image histogram equalization do applet can help to learn basic knowledge of image processing)

三次样条曲线拟合类，可用于样条插值、拟合、预测等算法场合。(The Cubic Spline Interpolation class can be used for spline interpolation, fitting, prediction and other algorithms.)

说明：  用分水岭算法进行图像分割，借鉴形态学理论，将一幅图看成拓扑性地图，其中灰度值对应地形高度。(The watershed algorithm is used for image segmentation, and a map is regarded as a topological map, in which the gray value corresponds to the terrain height.)
