Motion Tracking

Published:

Motion tracking, sometimes called object tracking, is a computer vision task that follows objects as they move through a video. After an object is detected, the system assigns it an ID and then updates its position from frame to frame. Tracking can be done with basic methods that follow bounding boxes or with more advanced approaches that rely on appearance cues and motion patterns to keep each object’s identity stable, even when objects overlap or briefly move out of view.

Motion tracking is used in sports analysis, autonomous driving, and video editing. It helps answer practical questions such as where a vehicle traveled or how many times a person passed a certain point. Performance is judged by how consistently the system maintains each object’s ID and how few objects it loses during tracking.
