Description: 本程序实现了基于质心法的目标跟踪，由于算法比较简单，因此背景颜色必须简单，最好是纯白色的。本程序先经过对视频图像的灰度化，二值化等一些图像处理，然后找出质心。程序中用到了Opencv库函数-Realize this procedure based on the quality of target tracking-force, due to relatively simple algorithm, so the need for a simple background color, the best was pure white. This procedure, after the first video images of gray and binary image processing, such as, and then find the center of mass. Procedures used in the library function Opencv

Description: hartigans Sequential Leader Clustering Algorithm in terms of OpenCV (ver.1.1)
Sequential Leader algorithm:
Hartigan, J. A. (1975), Clustering Algorithms. John Wiley and Sons, Inc., New York, NY.
1. Select maximum cluster "radius"
2. Start with zero clusters
3. Add each item to be clustered to:
* Closest cluster if distance <= r
* New cluster if distance to closest cluster > r
4. Compute new center from members in cluster
5. Empty the clusters (keeping the centers)
6. Return to step 3 (until no changes are made)

Description: 采用 CAMSHIFT 算法快速跟踪和检测运动目标的 C/C++ 源代码，OPENCV BETA 4.0 版本在其 SAMPLE 中给出了这个例子。算法的简单描述如下-This application demonstrates a fast, simple color tracking algorithm that can be used to track faces, hands . The CAMSHIFT algorithm is a modification of the Meanshift algorithm which is a robust statistical method of finding the mode (top) of a probability distribution. Both CAMSHIFT and Meanshift algorithms exist in the library. While it is a very fast and simple method of tracking, because CAMSHIFT tracks the center and size of the probability distribution of an object, it is only as good as the probability distribution that you produce for the object. Typically the probability distribution is derived from color via a histogram, although it could be produced from correlation, recognition scores or bolstered by frame differencing or motion detection schemes, or joint probabilities of different colors/motions etc.
In this application, we use only the most simplistic approach: A 1-D Hue histogram is sampled from the object in an HSV color space version of the image. To produce the

Description: 使用opencv去掉二值化图像中黑色面积较小的连通域。
程序中语句 tmparea = fabs(cvContourArea(contour)) 可以得到当前连通域的面积，当此面积小于阈值时对其填充为白色。
rect = cvBoundingRect(contour,0) 得到的是框住连通域的最小矩形，对矩形中的黑色部分将其填充为白色，但是这样的话，连通域6和4两个连通域被填充成了白色的矩形，这显然不符合我们的要求，这样就要判断此连通域是黑色联通域还是白色连通域，采用的方法是测试矩形的中心点，如果其为黑色，则认为此连通域是黑色连通域，否则为白色联通域，对于黑色联通域我们对其进行白色填充处理，对于白色联通域则保持不变。-Using opencv binary image to remove the black connected components smaller.
Program statement tmparea = fabs (cvContourArea (contour)) can get the current connected component of the area, when this area is less than the threshold when it filled with white.
rect = cvBoundingRect (contour, 0) get is a box to live in the smallest rectangle connected domains, part of the black rectangle to fill with white, but this is the case, connected components 6 and 4 are filled into two connected components of white rectangle, which obviously does not meet our requirements, so we must determine if the connected domain is black or white Unicom domain connected domain, the approach is to test the center of the rectangle, if it is black, is that the black connected components connected domain, otherwise the domain of white Unicom, China Unicom for the black white fill field we deal with them, for the white Unicom domain remains unchanged.
