SoccerNet Jersey Number Recognition

Repository containing all necessary codes to get started on the SoccerNet Jersey Number Recognition challenge.

In this year's SoccerNet Jersey Number challenge, participants are given short video tracklets of soccer players and are asked to identify the jersey number of the player. This task can be useful for consumer applications as it helps to build systems that can accurately identify and recognize players in real-time during a soccer game. This information can be used to create interactive experiences for fans, such as player statistics, player tracking, and in-game analysis. Additionally, this technology can also be used in broadcast production to add player labels and enhance the viewing experience. By encouraging research on player recognition, the SoccerNet Jersey Number challenge contributes to the development of more engaging and informative consumer applications for soccer fans.

2023 Challenge Leaderboard

Description of the task

Given short video tracklets of soccer players that can be a few hundreds frames long, the participants are asked to identify the jersey number of each player (Players with non visible jersey numbers are annotated with the "-1" value). The task is challenging because of the low quality of the thumbnails (low resolution, high motion blur) and because the jersey numbers might be visible on a very small subset of the whole tracklet.

How to download the dataset

The SoccerNet Jersey Number dataset is composed of 2853 tracklets of players extracted from the SoccerNet tracking videos. The challenge set is composed of 1211 separate players tracklets with hidden annotations.

A SoccerNet pip package to easily download the data and the annotations is available.

To install the pip package simply run:

<code>pip install SoccerNet</code>

Then use the API to downlaod the data of interest:

from SoccerNet.Downloader import SoccerNetDownloader as SNdl
mySNdl = SNdl(LocalDirectory="path/to/SoccerNet")
mySNdl.downloadDataTask(task="jersey-2023", split=["train","test","challenge"])

Dataset format

Dataset is split into three folders: train/test/challenge. Each folder contains a json grountruth file (except the challenge set) and an "image" folder. In the image folder, there is one folder per player with a list of thumbnails: each folder is named after the player ID. The groundtruth json file is a one level python dictionnary with player ID (a String) as keys and player jersey number (an Integer) as value. A value of "-1" is used to indicate the jersey number is not visible.

Submission format

The file to submit for the challenge/test set on EvalAI must have the same format as the ground truth file: a dictionnary mapping player ID (a String) to player jersey number (an Integer). A value of "-1" must be used to indicate the jersey number is not visible.
