SFSORT: Scene Features-based Simple Online Real-Time Tracker
This work addresses the need for real-time, efficient multi-object tracking in computer vision applications, representing an incremental improvement with specific speed and accuracy gains.
The paper tackles multi-object tracking by introducing SFSORT, a fast online tracker that achieves an HOTA of 61.7% at 2242 Hz on MOT17 and 60.9% at 304 Hz on MOT20, using a novel cost function and scene features to eliminate the Kalman Filter.
This paper introduces SFSORT, the world's fastest multi-object tracking system based on experiments conducted on MOT Challenge datasets. To achieve an accurate and computationally efficient tracker, this paper employs a tracking-by-detection method, following the online real-time tracking approach established in prior literature. By introducing a novel cost function called the Bounding Box Similarity Index, this work eliminates the Kalman Filter, leading to reduced computational requirements. Additionally, this paper demonstrates the impact of scene features on enhancing object-track association and improving track post-processing. Using a 2.2 GHz Intel Xeon CPU, the proposed method achieves an HOTA of 61.7\% with a processing speed of 2242 Hz on the MOT17 dataset and an HOTA of 60.9\% with a processing speed of 304 Hz on the MOT20 dataset.
