Web13 de fev. de 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 … Web3 de fev. de 2024 · On the sample that was presented on the OpenCV's website, one of the inputs of the function calcOpticalFlowPyrLK() was cv2.goodFeaturesToTrack. I wanted to change that input to an output I have acquired from my another function. But the outputs of those two functions are mainly different in type.
