How does the Lucas Kanade algorithm work?
It works by trying to guess in which direction an object has moved so that local changes in intensity can be explained. Assume that we watch a scene through a square hole. The intensity a visible through the hole is variable. In the next frame the intensity of the pixel has increased to b.
Which algorithm is best for object tracking?
DeepSORT is one of the most popular object tracking algorithms. It is an extension to Simple Online Real-time Tracker or SORT, which is an online-based tracking algorithm. SORT is an algorithm that uses the Kalman filter for estimating the location of the object given the previous location of the same.
How do I track a specific object in a video?
1. What is Video Object Tracking? In Video Object Tracking, the aim is to locate one or multiple objects of interest (the “targets”) in each frame of a video. We usually locate the target by drawing the smallest rectangle possible (the “bounding box”) in which it is included.
What is tracking by detection?
The tracking-by-detection method involves an independent detector that is applied to all image frames to obtain likely detections, and then a tracker, which is run on the set of detections. Hereby, the tracker attempts to perform data association (for example, linking the detections to obtain complete trajectories).
