ARC‑SORT is a real‑time, training‑free multi‑object tracker designed for fast, direction‑changing athletes in sports broadcasts. It uses an Interacting Multiple Model Kalman filter to generate per‑track uncertainty‑adaptive search regions (EIoU) and a lightweight corrective identity swap mechanism for track crossings, achieving high HOTA scores on SportsMOT and DanceTrack. The tracker also drops the motion gate for long‑absent players, linking tracklets solely by appearance, and runs at ~50 fps on an RTX 3060 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."

arXiv:2607. 11548v1 Announce Type: cross Abstract: Spatial football metrics such as pitch control assume access to the positions of all 22 players, yet the most widely available source of positional data -- the broadcast main camera -- shows only 10-16 of them at any moment.
