I am trying to set the waitKey in such a way that it will allow the video to play at the correct frame rate. However the variable FPS is reporting back 18 to 22. What is the reason for this? WebFeb 13, 2024 · In this tutorial, we will learn Object tracking using OpenCV. A tracking API that was introduced in OpenCV 3.0. We will learn how and when to use the 8 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 …
