SoccerNet 2023 Tracking Challenge -- 3rd place MOT4MOT Team Technical Report
The SoccerNet 2023 tracking challenge requires the detection and tracking of
soccer players and the ball. In this work, we present our approach to tackle
these tasks separately. We employ a state-of-the-art online multi-object
tracker and a contemporary object detector for player tracking. To overcome the
limitations of our online approach, we incorporate a post-processing stage
using interpolation and appearance-free track merging. Additionally, an
appearance-based track merging technique is used to handle the termination and
creation of tracks far from the image boundaries. Ball tracking is formulated
as single object detection, and a fine-tuned YOLOv8l detector with proprietary
filtering improves the detection precision. Our method achieves 3rd place on
the SoccerNet 2023 tracking challenge with a HOTA score of 66.27.Comment: 3 pages, 1 figur
SoccerNet 2023 Challenges Results
peer reviewedThe SoccerNet 2023 challenges were the third annual video understanding
challenges organized by the SoccerNet team. For this third edition, the
challenges were composed of seven vision-based tasks split into three main
themes. The first theme, broadcast video understanding, is composed of three
high-level tasks related to describing events occurring in the video
broadcasts: (1) action spotting, focusing on retrieving all timestamps related
to global actions in soccer, (2) ball action spotting, focusing on retrieving
all timestamps related to the soccer ball change of state, and (3) dense video
captioning, focusing on describing the broadcast with natural language and
anchored timestamps. The second theme, field understanding, relates to the
single task of (4) camera calibration, focusing on retrieving the intrinsic and
extrinsic camera parameters from images. The third and last theme, player
understanding, is composed of three low-level tasks related to extracting
information about the players: (5) re-identification, focusing on retrieving
the same players across multiple views, (6) multiple object tracking, focusing
on tracking players and the ball through unedited video streams, and (7) jersey
number recognition, focusing on recognizing the jersey number of players from
tracklets. Compared to the previous editions of the SoccerNet challenges, tasks
(2-3-7) are novel, including new annotations and data, task (4) was enhanced
with more data and annotations, and task (6) now focuses on end-to-end
approaches. More information on the tasks, challenges, and leaderboards are
available on https://www.soccer-net.org. Baselines and development kits can be
