"The intuition behind the meanshift is simple. Consider you have a set of points. (It can be a pixel distribution like histogram backprojection). You are given a small window (may be a circle) and you have to move that window to the area of maximum pixel density (or maximum number of points). It is illustrated in the … Ver mais In this chapter, 1. We will learn about the Meanshift and Camshift algorithms to track objects in videos. Ver mais Did you closely watch the last result?
