SoccerNet - Replay Grounding

Welcome to the SoccerNet Development Kit for the Replay Grounding Task and Challenge. This kit is meant as a help to get started working with the soccernet data and the proposed task. More information about the dataset can be found on our official website.

SoccerNet Replay Grounding is part of the SoccerNet-v2 dataset, which is an extension of SoccerNet-v1 with new and challenging tasks including action spotting, camera shot segmentation with boundary detection, and a novel replay grounding task.

The Action Spotting dataset consists of 500 complete soccer games including:

• Full untrimmed broadcast videos in both low and high resolution.
• Pre-computed features such as ResNET-152.
• Annotations of camera changes and replays with live action spot (Labels-cameras.json).

Participate in our upcoming Challenge in the CVPR 2022 International Challenge on Activity Recognition Workshop and try to win up to 500$ sponsored by SportRadar! All details are available on the challenge website, or on the main page.

The participation deadline is fixed at the 30th of May 2022. The official rules and guidelines are available on ChallengeRules.md.

How to download the dataset

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
mySoccerNetDownloader = SoccerNetDownloader(LocalDirectory="/path/to/SoccerNet")
mySoccerNetDownloader.downloadGames(files=["Labels-cameras.json"], split=["train","valid","test"])

If you want to download the videos, you will need to fill a NDA to get the password.

mySoccerNetDownloader.password = input("Password for videos?:\n")
mySoccerNetDownloader.downloadGames(files=["1_224p.mkv", "2_224p.mkv"], split=["train","valid","test","challenge"])
mySoccerNetDownloader.downloadGames(files=["1_720p.mkv", "2_720p.mkv", "video.ini"], split=["train","valid","test","challenge"])

We provide several features including ResNET (used for our benchmarks), and last year's winners features from Baidu Research. Check out our pip package documentation for more features.

mySoccerNetDownloader.password = input("Password for videos?:\n")
mySoccerNetDownloader.downloadGames(files=["1_ResNET_TF2_PCA512.npy", "2_ResNET_TF2_PCA512.npy"], split=["train","valid","test","challenge"])
mySoccerNetDownloader.downloadGames(files=["1_baidu_soccer_embeddings.npy", "2_baidu_soccer_embeddings.npy", "video.ini"], split=["train","valid","test","challenge"])

How to extract video features

As it was one of the most requested features on SoccerNet-V1, check out the action spotting repository to extract the features.

Benchmark Implementations

This repository contains several benchmarks for replay grounding, which are presented in the SoccerNet-V2 paper. You can use these codes to build upon our methods and improve the performances.

Evaluation

This repository and the pip package provide evaluation functions for the proposed tasks based on predictions saved in the JSON format. See the Evaluation folder of this repository for more details.

Visualizations

Finally, this repository provides the Annotation tool used to annotate the camera changes and replays. This tool can be used to visualize the information. Please follow the instruction in the dedicated folder for more details.
