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 Platform: |

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.
