说明：  使用gpu、cpu并行进行sift算子计算匹配，能够在原来的基础上加速处理，但对显卡要求较高，具体环境配置使用方法可以参照mannual(SiftGPU is an implementation of SIFT [1] for GPU. SiftGPU processes pixels parallely to build Gaussian pyramids and detect DoG Keypoints. Based on GPU list generation[3], SiftGPU then uses a GPU/CPU mixed method to efficiently build compact keypoint lists. Finally keypoints are processed parallely to get their orientations and descriptors. SiftGPU is inspired by Andrea Vedaldi s sift++[2] and Sudipta N Sinha et al s GPU-SIFT[4] . Many parameters of sift++ ( for example, number of octaves, number of DOG levels, edge threshold, etc) are also available in SiftGPU. The shader programs are dynamically generated according to the parameters that user specified. SiftGPU also includes a GPU exhaustive/guided sift matcher SiftMatchGPU. It basically multiplies the descriptor matrix on GPU and find closest feature matches on GPU. Both GLSL and CUDA implementations are provided. )

还是关于电子海图的demo，是关于中心旋转地图的，望通过！谢谢(Still on the electronic chart demo, is rotated about the center of the map, look through! Thank you)

实现了直线和矩形框的裁剪功能，是用编码裁剪原理实现的(Achieved a straight line and cut features a rectangular box is the use of coding theory to achieve cutting)

openCV+MFC（VS2008）canny边缘检测，能用滑动条调节参数(openCV+MFC (VS2008) canny edge detection, use the slider to adjust parameters)

卡尔曼滤波的完整C++源代码，非常全，内含matlab相关的程序，使用时请结合具体状态方程。(Kalman filtering the complete source code, very full.)

语法分析器构造 借助于词法分析程序提供的分析结果，编写一个算符优先语法分析程序，程序能进行语法结构分析和错误检查并产生相应的归约信息。同时给出出错信息和错误类型，从而加深对语法分析的理解。 (parser using lexical analysis procedure for the analysis of results prepare a priority operator syntax analysis procedures, procedures for structural analysis and syntax error checking and produce corresponding reduction information. Also given wrong information and the wrong types, so as to enhance the understanding of syntax analysis.)

自己用VC编写的GIS中voronoi图和凸壳自动生成源代码(Their use of VC in the preparation of GIS maps and Convex Hull voronoi automatically generated source code)

Visual C++ 与Matlab混合编程，可以让Visual C++程序员快速进行matlab编程(Visual C++ with matleb combine pragraming )

通过数字图像相关的方法计算两幅图像之间的位移，计算时间较长，是最基础的DIC，没有优化。(Digital image correlation method to calculate the displacement between the two images, the time is longer, is the most basic DIC, no optimization.)
