This article gives a more robust justification for the use of the Bhattacharyya distance in the algorithm used by our Automated Sport Analysis System named ACE in the first of its three perception modules. Such first module consists in the temporal segmentation of television video broadcasts, aiming to break down the video into shots, delimited by scene boundaries. An evaluation of other seven histogram...
In soccer matches, 3D reconstruction is a main part of many applications including free-viewpoint broadcasting, match analysis, augmented reality, and refereeing examination. The main challenge of 3D reconstruction in soccer scenes is the human body reconstruction. Although 3D reconstruction methods have been improved to a high extent in controlled condition, still there are lots of uncovered issues...
In this paper, we propose a novel, fully automatic method to obtain accurate view synthesis for soccer games. Existing methods often make assumptions about the scene. This usually requires manual input and introduces artifacts in situations not handled by those assumptions. Our method does not make assumptions about the scene; it solely relies on feature detection and utilizes the structures visible...
During this year's World Cup, several innovative IT applications were deployed for the first time, reshaping how officials make decisions, how broadcasters cover live events, and how fans immerse themselves in the game.
Indoor soccer has been of tactical and scientific interest, with applications dedicated to analyze tactical and physiological factors and also physical training. In both cases, the analysis is based on player tracking, done with human supervision. This paper presents an automatic tracking method which shows the trajectories of indoor soccer players during the game and saving skilled labor during the...
In this paper, we propose a method to track multiple players in a football match video which is captured by a single camera. The camera pans and brings the players and the ball into the view, enabling to record the whole pitch. The players' trajectories in frames and camera movement are obtained to estimate the trajectories on the pitch. Moreover, we propose an effective tracking method for solving...
3DTV production of live sports events presents a challenging problem involving conflicting requirements of maintaining broadcast stereo picture quality with practical problems in developing robust systems for cost effective deployment. In this paper we propose an alternative approach to stereo production in sports events using the conventional monocular broadcast cameras for 3D reconstruction of the...
Camera parameters estimation is an important issue in machine vision research area. This paper proposes a new method to find pan and tilt of camera in sport scene on the basis of vanishing points. Vanishing point (VP) of parallel lines is the image of the point at infinity, which corresponds to the projection of the intersection of parallel lines at infinity. According to projective geometry constraint,...
Videos of multi-player team sports provide a challenging domain for dynamic scene analysis. Player actions and interactions are complex as they are driven by many factors, such as the short-term goals of the individual player, the overall team strategy, the rules of the sport, and the current context of the game. We show that constrained multi-agent events can be analyzed and even predicted from video...
