It is a centroid-based algorithm, which works by updating candidates for centroids to be the mean of the points within a given region. WebApr 5, 2024 · 2. Track object and Mean-shift. Having found a way to identify the object, we need to keep track of the positions and memorize them. For this purpose, we use the meanShift OpenCV function. You can learn more about tutorial meanshift. In the code below I show how this can be called and used in real conditions.
