rePost: (Primary Assumption of Centroid Tracking Algorithm):Simple object tracking with OpenCV – PyImageSearch

The primary assumption of the centroid tracking algorithm is that a given object will potentially move in between subsequent frames, but the distance between the centroids for frames and will be smaller than all other distances between objects. Therefore, if we choose to associate centroids with minimum distances between subsequent frames we can build our object tracker.
