TVCalib: Camera Calibration for Sports Field Registration in Soccer

1 code implementation24 Jul 2022 Jonas Theiner, Ralph Ewerth

Sports field registration in broadcast videos is typically interpreted as the task of homography estimation, which provides a mapping between a planar field and the corresponding visible area of the image.

Extraction of Positional Player Data from Broadcast Soccer Videos

no code implementations21 Oct 2021 Jonas Theiner, Wolfgang Gritz, Eric Müller-Budack, Robert Rein, Daniel Memmert, Ralph Ewerth

A comprehensive experimental evaluation is presented for the individual modules as well as the entire pipeline to identify the influence of errors to subsequent modules and the overall result.

A Unified Taxonomy and Multimodal Dataset for Events in Invasion Games

1 code implementation25 Aug 2021 Henrik Biermann, Jonas Theiner, Manuel Bassek, Dominik Raabe, Daniel Memmert, Ralph Ewerth

To address these issues, we present (1) a universal taxonomy that covers a wide range of low and high-level events for invasion games and is exemplarily refined to soccer and handball, and (2) release two multi-modal datasets comprising video and positional data with gold-standard annotations to foster research in fine-grained and ball-centered event spotting.

Benchmarking Video Classification

Interpretable Semantic Photo Geolocation

1 code implementation30 Apr 2021 Jonas Theiner, Eric Mueller-Budack, Ralph Ewerth

State-of-the-art methods treat the task as a classification problem, where the choice of the classes, that is the partitioning of the world map, is crucial for the performance.

Multimodal Analytics for Real-world News using Measures of Cross-modal Entity Consistency

no code implementations23 Mar 2020 Eric Müller-Budack, Jonas Theiner, Sebastian Diering, Maximilian Idahl, Ralph Ewerth

In this paper, we introduce a novel task of cross-modal consistency verification in real-world news and present a multimodal approach to quantify the entity coherence between image and text.
