Meanshift in OpenCV. To use meanshift in OpenCV, first we need to setup the target, find its histogram so that we can backproject the target on each frame for calculation of meanshift. We also need to provide an initial location of window. For histogram, only Hue is considered here. See more In this chapter, 1. We will learn about the Meanshift and Camshift algorithms to track objects in videos. See more The intuition behind the meanshift is simple. Consider you have a set of points.
