Following specific objects through footage to apply effects or replacements.
Definition
Object Tracking tracks defined objects (not just points) through footage. The tracking data allows effects, replacements, or information to be bound to the object.
Practical Application
Screen replacement on phones/tablets. Logo insertion on clothing. Object removal with a clean plate. Face tracking for beauty/VFX. Product placement in post-production.
Technical Details
2D vs. 3D Object Tracking. Bounding box or precise contour. Occlusion handling for obscured objects. Machine learning (e.g., Track Everything) is revolutionizing object tracking.
