An Introduction to Object Tracking

Common challenges with object tracking and different techniques for object tracking

What is Object Tracking?

Object tracking is a technique to identify objects of interest in a video, assigning a unique Id to each distinct identified object as they move. The object tracking for an object with a unique Id starts when the object enters the scene and ends when the object leaves the scene.

Object tracking aims to accurately identify objects of interest, estimate their trajectories in videos and track them as they move. Tracking determines whether an object is the same as in the previous frames.

Object Tracking is composed of

• Object Detection and Recognition: A technique to identify and localize the objects of interest by bounding boxes in each frame
• Object Tracking: Generating a unique ID for each detected object, tracking them as they move around in a video while maintaining the ID assignment.

Application of Object Tracking

• Autonomous driving to track cars and other obstacles to can plan a route and avoid collision
• Traffic control detects moving vehicles and correctly recognizes their model, make, and brand type for important traffic information.
• Digital forensics includes criminal and online forensic tracking for single or multiple…
