Feature Tracking

Feature tracking is a process used in computer vision to identify and follow specific points or patterns in a sequence of images or video frames. It involves detecting distinctive visual features—like corners or edges—and then monitoring their movement over time. This technique helps understand motion, analyze object behavior, or create smooth visual effects. Essentially, feature tracking captures how particular points shift across frames, enabling machines to interpret dynamic scenes, track objects, or reconstruct 3D environments more accurately.
