ARC‑SORT is a real‑time, training‑free multi‑object tracker designed for fast, direction‑changing athletes and dynamic camera motion in sports broadcasts. It uses an Interacting Multiple Model Kalman filter to adaptively size search regions based on per‑track uncertainty, and applies a single corrective identity swap after track crossings when appearance evidence indicates a mistake. The method achieves state‑of‑the‑art HOTA scores on SportsMOT and DanceTrack while running at ~50 fps on a laptop GPU.

The paper introduces a deployment‑focused evaluation protocol for pedestrian tracking that isolates tracker performance by using shared detections, assessing initialization, gap continuation, identity recovery, close‑neighbor association, and runtime under load, while still reporting HOTA as an aggregate metric. Applied to the JackRabbot Dataset, the protocol reveals that trackers vary widely in capability, with none maintaining spatially correct, same‑identity output after 1 s of missing detector support, and that runtime on an NVIDIA Jetson Orin often falls below the 10 Hz target in crowded scenes. The authors provide open‑source code and scripts to enable reproducible assessment of tracker suitability for real‑world pedestrian‑centric robotics.
whyItMatters":"The protocol offers a practical, tracker‑only framework that directly informs the design and deployment of mobile robots operating among pedestrians by highlighting specific failure modes and computational constraints that aggregate scores overlook."
