opencv圆检测

提供两种抽取视频帧的方法，一种为逐帧遍历，输出所需要的关键帧，另一种为预先设置帧号，直接从视频中抽取，两种方法适用场合不同，各有长处。

用张正有的方法实现摄像机内参数标定,经验证可以实现(Zhang is some method to achieve with camera calibration parameters within)

经典的opencv学习代码，深入理解opencv一书的示例代码，包含了9章的内容

车辆检测系统，用opencv和C++实现汽车流量的检测。(Vehicle detection system, with car traffic detection opencv and C++ implementation.)

目标跟踪算法，基于kalman滤波的meanshift目标跟踪算法(With the rapid development of hardware and software technology and machine intelligence at home and abroad, more and more attention has been paid to the research subject of computer vision. People have begun to have a rich interest in visual information. Vision is an important part of various applications, such as medical diagnosis, military analysis, and aerospace intelligent systems. At the same time, a large number of researchers have done a variety of research on computer vision, including video based targets.)

说明：  vs opencv实现图像去雾处理vs opencv实现图像去雾处理(Image de fogging with vs opencv)

采用opencv开发，先利用线扫描确定ROI区域，然后矫正位置后进行异物分析，准确率100%,单个检测时间在10ms 以内。

matlab程序进行图像分割，图像的多阈值分割(Matlab program for image segmentation, image multi-threshold segmentation)

采用canny算子进行边缘检测，小阈值控制边缘连接，大阈值控制边缘的初始分割(Canny operator used for edge detection, edge linking a small threshold control, threshold control large initial segments of the edge)

opencv环境下，系统能够在窗口抓捕获图像并保存为灰度格式或者真彩格式，并且存储下来。(Set up your system to capture and display live video in a window. Access each frame and do any operations you want to the frame pixels.)
