SORT vs DeepSORT vs ByteTrack vs OC-SORT: Which Tracking Algorithm Should You Use?

Object tracking extends frame-by-frame detectors such as RF-DETR by associating detections over time and assigning persistent IDs, typically through detection, motion prediction, matching, and track management. SORT offers a fast, lightweight baseline using Kalman-filter motion prediction, IoU matching, and the Hungarian algorithm, but may lose identities during occlusions or crossings. DeepSORT adds neural-network appearance features and a matching cascade, improving identity preservation in crowded scenes at greater computational cost. ByteTrack improves recovery of blurred, partially hidden, or uncertain objects by matching tracks first to high-confidence detections and then to low-confidence ones, while OC-SORT uses observed motion direction and recovery mechanisms to better address occlusions and nonlinear or sudden movement. The appropriate tracker depends on footage characteristics: SORT suits simple predictable scenes, DeepSORT crowded identity-sensitive settings, ByteTrack low-confidence detections, and OC-SORT irregular motion. Roboflow Workflows and Agent can be used to create, test, customize, and deploy tracking pipelines through a visual or natural-language interface, with support for cloud deployment or local hardware such as NVIDIA Jetson and Raspberry Pi.
