Centroids are computed based on the down sampled frame. In the context of hand gesture tracking, the following points highlights how the centroid tracking is implemented to separated gestures and its advantages: When there is no significant motion of the centroid, the system initiates the gesture and ends it when the centroid comes to a halt. The centroid tracking algorithm assumes that we are passing in a set of bounding box (x, y) -coordinates for each detected object in every single frame. The second methodology, centroid tracking, is based on identifying and tracking the centroid of every single cell within a convective system, obtaining other properties, such as the intensity, vertical integrated liquid (VIL), or top height, among others.
