Real-time camera pose estimation for sports fields

Pascal Fua, Charles Dubout, Horesh Beny Ben Shitrit, Pablo Marquez Neila, Stefano Savarè, Leonardo Citraro

Given an image sequence featuring a portion of a sports field filmed by a moving and uncalibrated camera, such as the one of the smartphones, our goal is to compute automatically in real time the focal length and extrinsic camera parameters for each image ...

Parsing human skeletons in an operating room

Pascal Fua, Slobodan Ilic, Horesh Beny Ben Shitrit, Vasileios Belagiannis, Xinchao Wang

Multiple human pose estimation is an important yet challenging problem. In an Operating Room (OR) environment, the 3D body poses of surgeons and medical staff can provide important clues for surgical workflow analysis. For that purpose, we propose an algor ...

Take your Eyes off the Ball: Improving Ball-Tracking by Focusing on Team Play

Pascal Fua, Horesh Beny Ben Shitrit, Xinchao Wang, Vitaly Henry Ablavsky

Accurate video-based ball tracking in team sports is important for automated game analysis, and has proven very difficult because the ball is often occluded by the players. In this paper, we propose a novel approach to addressing this issue by formulating ...

Multi-Commodity Network Flow for Tracking Multiple People

Pascal Fua, Jérôme Berclaz, François Fleuret, Horesh Beny Ben Shitrit

In this paper, we show that tracking multiple people whose paths may intersect can be formulated as a multi-commodity network flow problem. Our proposed framework is designed to exploit image appearance cues to prevent identity switches. Our method is effe ...

Tracking Multiple Players using a Single Camera

Pascal Fua, François Fleuret, Horesh Beny Ben Shitrit, Mirko Raca

It has been shown that multi-people tracking could be successfullly formulated as a Linear Program to process the output of multiple fixed and synchronized cameras with overlapping fields of view. In this paper, we extend this approach to the more challeng ...

Tracklet-based Multi-Commodity Network Flow for Tracking Multiple People

Pascal Fua, Jérôme Berclaz, François Fleuret, Horesh Beny Ben Shitrit

(EN)A method for continuously tracking multiple people partitioned into groups while preserving identities under global appearance constraints, wherein people's trajectories may intersect, and wherein only sparse appearance information is available is disc ...

Tracking Multiple People under Global Appearance Constraints

Pascal Fua, Jérôme Berclaz, François Fleuret, Horesh Beny Ben Shitrit

In this paper, we show that tracking multiple people whose paths may intersect can be formulated as a convex global optimization problem. Our proposed framework is designed to exploit image appearance cues to prevent identity switches. Our method is effect ...

Long Term Real Trajectory Reuse Through Region Goal Satisfaction

Ronan Boulic, Daniel Thalmann, Pascal Fua, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre, Horesh Beny Ben Shitrit, Mirko Raca

This paper is motivated by the objective of improving the realism of real-time simulated crowds by reducing short term collision avoidance through long term anticipation of pedestrian trajectories. For this aim, we choose to reuse outdoor pedestrian trajec ...
