(6)多目标跟踪查找算法(Multiple object track finding algorithms):当我们有一个快速的目标检测器时,在每一帧中检测多个对象,然后运行一个跟踪查找算法来识别一个帧中的哪个矩形与下一个帧中的矩形相对应是有意义的。 二、Tracking VS Detection 如果你玩过OpenCV人脸检测,你就会知道它是实时工作的,你可以很容易地...

3.MultiTracker的add方法 vector<Rect2d>obj;vector<Ptr<Tracker>>algorithms;for(autoi=0;i<rois.size();i++){obj.push_back(rois[i]);algorithms.push_back(TrackerKCF::create());}trackers.add(algorithms,frame,obj); 在多目标的API里面,用add方法代替了init方法,给trackers传入每个ROI的跟踪器和边界框。

OpenCV (Open Source Computer Vision Library: http://opencv.org) is an open-source library that includes several hundreds of computer vision algorithms. The document describes the so-called OpenCV 2.x API, which is essentially a C++ API, as opposed to the C-based OpenCV 1.x API (C API ...

tracking methods are not enough, sometimes result in error trace. In view of this, based on the particle filter tracking algorithm, improving proposed location--color histogram basedparticle filter tracking algorithm and improved algorithms at the same time. Finally, many experimental analysis of the...
