a Histogram of the computation times for the modules in the MOT system when processing an MOT benchmark sequence (600 frames) titled “MOT17-02-FRCNN”62,63 (CC BY-NC-SA 3.0 License). The inset shows a timing chart illustrating the overlapping operation of the detector and the other tracking modules. b A scene from “MOT17-02-FRCNN” with tracks indicated as bounding boxes. Facial regions have been blurred to protect privacy. c, d, e Five-object tracking through a complex occlusion event involving simultaneous occurrences of three-object crossing and two-object crossing, where the scenes in (c, d, e) show, respectively, the frames #50, #80, and #110 extracted from a sequence (142 frames) provided as the Supplementary Movie 2. The movie was generated using CARLA simulator (MIT License) and assets (CC-BY License)64. The bounding boxes indicate tracks. f, g, h Similarity matrices corresponding to c, d, e, with red and blue boxes indicating the assignment results between tracks and detections.
