灰度图像直方图的计算，超级好用的啊，可以通过它获得图像的分形维数等等，内存小，功能大(Gray image histogram calculation, super nice ah, you can get through it the fractal dimension of the image, and so on, the memory is small, functional large)

将曲线轮廓中的B-样条曲线通过最小二分法转换成一组能保持曲线轮廓形状的小折线。这样，原有的字体轮廓数据就从用曲线轮廓表示转变为用多边形表示，即用一组点及其先后顺序来描述轮廓。(Profile to Polygon)

序列匹配c++实现，可以帮助理解序列匹配算法(Sequence matching c++ implementation can help to understand the sequence matching algorithm)

说明：  平台基于visual studio2015，使用opencv函数实现高斯滤波，进行图像处理(gaussian blur based on opencv)

本代码主要关于摄影测量中的单向空间后方交会(resection of photogrammetry)

针对目前工业制造领域面临的难题,提出利用非量测数字摄像机进行工业钣金件高精度三维重建与视觉检测.采用二维直接线性变换分解摄像机参数初值并结合光束法平差进行高精度标定 利用最小二乘模板匹配提取像面上的点、直线信息并进行混合光束法平差,从而进行钣金件的高精度三维重建及其尺寸制造误差的检测.所开发的视觉检测系统硬件成本低、自动化程度较高,实际数据的多次实验均取得了优于1/8 000的相对精度,说明所论述的方法为工业零件的自动化三维检测提供了一条可行途径.(View of the current challenges facing the field of industrial manufacturing, made use of non-metric digital camera precision sheet metal parts for industrial reconstruction and visual inspection. Using two-dimensional direct linear transformation and the decomposition of initial parameters of the camera bundle adjustment with high accuracy calibration extracted by the least square template matching, like the surface of point, line information and mixed bundle adjustment to the three-dimensional reconstruction of high-precision sheet metal parts and the size of the detection of manufacturing errors. visual inspection system developed by the hardware low cost, high degree of automation, the actual data, many experiments have achieved better than 1/8000 of the relative accuracy, that the methods discussed in the automation of industrial components to provide a feasible three-dimensional detection approach.)

关于车辆跟踪的c++程序，使用了opencv进行跟踪，采用了帧差方法效果还不错(vehicle detection)

vc++编写的鼠标键盘消息的拦截程序，运用钩子实现(vc++ prepared to intercept mouse messages keyboard procedures, the use of hook realize)
