Remarks

For Beginners: SORT is a simple yet effective online tracking algorithm that uses Kalman filtering for state estimation and the Hungarian algorithm for detection-to-track association based on IoU overlap.

Key features: - Kalman filter for motion prediction - IoU-based association using Hungarian algorithm - No appearance features (pure motion-based) - Real-time performance (~260 FPS)
