WebDescription. The point tracker object tracks a set of points using the Kanade-Lucas-Tomasi (KLT), feature-tracking algorithm. You can use the point tracker for video stabilization, camera motion estimation, and object tracking. It works particularly well for tracking objects that do not change shape and for those that exhibit visual texture. WebThis function should be called once every time step, before `update`.

WebSep 10, 2024 · Following object detection, various methods, including MIL, KCF, CSRT, GOTURN and Median Flow can be used to carry out object tracking. For tracking of multiple objects using any such method, OpenCV supplies multi-tracker objects to carry out frame-to-frame tracking of a set of bounding boxes until further action or failure. WebHuman pose estimation represents a graphical skeleton of a human. It helps to analyze the activity of a human. The skeletons are basically a set of coordinates that describe the pose of a person. Each joint is an individual coordinate that is known as a key point or pose-landmark. And the connection between key points is known as pair.
