Tracking-by-Detection

A common approach that performs object detection on each frame and builds tracks by associating detections over time.

Tracking-by-detection is one of the most common architectural patterns in modern tracking systems. Objects detected in each frame are associated with later detections using motion and appearance cues. Because the design is modular, detection and tracking components can be improved separately. However, detection errors can propagate and significantly affect tracking quality.
