In this tutorial, we will learn to track objects using OpenCV. OpenCV 3.0 began to introduce the tracking API. We will learn how and when to use the eight different trackers available in OpenCV 4.2 - BOOSTING, MIL, KCF, TLD, MEDIANFLOW, GOTURN, MOSSE and CSRT. We will also learn the general theory behind modern tracking algorithms. 1. What is ...
