Trajectory-based handball video understanding

Alexandre Hervieu, Patrick Bouthemy, Jean-Pierre Le Cadre
2009 Proceeding of the ACM International Conference on Image and Video Retrieval - CIVR '09  
This paper presents a content-based approach for understanding handball videos. Tracked players are characterized by their 2D trajectories in the court plane.  ...  The trajectories and their interactions are used to model visual semantics, i.e., the observed activity phases.  ...  Günsel et al. proposed a video indexing framework based on the analysis of "video objects" [2] .  ...

Does the Level of Graphical Detail of a Virtual Handball Thrower Influence a Goalkeeper's Motor Response?

Nicolas Vignais, Benoit Bideau, Cathy Craig, Sébastien Brault, Franck Multon, Paul Delamarche, Richard Kulpa
2009 Journal of Sports Science and Medicine  
The authors investigated how different levels of detail (LODs) of a virtual throwing action can influence a handball goalkeeper's motor response.  ...  However the kinematics of the motion revealed that the trajectory of the stopping limb was significantly different when comparing the L1 and L3 levels, and when comparing the L1 and L4 levels.  ...  Given these advantages of virtual reality over video, this technology has been exploited to analyze and understand players' performance in different sports such as soccer (Craig et al., 2006) , handball  ...

An overview of Human Action Recognition in sports based on Computer Vision

Kristina Host, Marina Ivašić-Kos
2022 Heliyon  
HAR aims to detect the person performing the action on an unknown video sequence, determine the action's duration, and identify the action type.  ...  Because of that, a novel systematization of actions based on complexity and level of performance and interactions is proposed.  ...  Apart from action recognition, the dataset can be used for other video understanding tasks such as text-video alignment and video highlight generation.  ...
