主要用于图像处理，局部二值模式，人脸识别方面(Mainly used for image processing, local binary patterns, face recognition area)

PCL是一个类似于OpenCV的开源库，提供了很多三维点云的处理功能，其中就包括点云拼接。在三维扫描项目中，需要利用点云拼接方法将多次扫描得到的点云数据拼合成一个整体。在本例中，用一幅包含人脸的深度图像去匹配之前获得的人脸模板，这将使我们能够确定人脸在场景中的位置和方向。(PCL is an open source library similar to OpenCV, which provides a lot of processing functions for three-dimensional point clouds, including point cloud mosaic. In the three-dimensional scanning project, it is necessary to use point cloud mosaic method to combine the point cloud data obtained from multiple scans into a whole. In this example, a depth image containing face is used to match the face template obtained before, which will enable us to determine the position and direction of the face in the scene.)

说明：  这是个qt绘制贝塞尔曲线的介绍文档，适合新手学习。(This is a QT drawing Bessel curve introduction document, suitable for novice learning.)

经过一系列步骤实现结构光的中心提取，结果还不错(After a series of steps, the center of structured light is extracted, and the result is not bad.)

实现一个简单的PCA降维与重构程序，用到的数据在.txt文件中。还有用于测试的.m文件(To achieve a simple PCA dimension reduction and reconstruction procedures)

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)

本系统实现指纹的识别和差异比对，通过差值程度来反映相似程度。(The system realizes fingerprint identification and difference alignment, and reflects the similarity degree by the degree of difference.)

基于盲解卷积的相位差算法，图像恢复，文件包里面有仿真和LBFGS优化算法(The phase difference based on blind deconvolution algorithm, vogel)

这是DCT的改进算法，可以提高DCT算法的执行速度。(This is the DCT of the improved algorithm can improve the execution speed DCT algorithms.)

利用matlab和ceemd进行编程求解简单的信息熵，根据求解的imf分量判断信号的情况(Using MATLAB and ceemd programming to solve simple information entropy, according to the IMF component to determine the situation of the signal)
