Contexte et atouts du poste
This postdoctoral position is part of the Inria International Relations Department's (DRI) annual postdoctoral recruitment campaign.
The postdoc will BE based in the VirtUs team at the Inria Centre at the University of Rennes. Frequent and/or long stays will also BE planned in the Virtual Environment and Computer Graphics (VECG) group at UCL in London.
The postdoc will BE supervised jointly by He Wang (UCL) and Julien Pettré (Inria).
The Inria Centre at Rennes University is one of Inria's eight centres and has more than thirty research teams. The Inria Centre is a major and recognized player in the field of digital sciences. IT is at the heart of a rich R&D and innovation ecosystem : highly innovative PMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute, etc. The VirtUs team has around 25 members, including 7 permanent researchers. The team is internationally recognized for its work in the fields of graphic animation and virtual reality. Crowd simulation and the study of collective human behavior is one of its major research themes.
Founded in 1826 in the heart of London, UCL is London's leading multidisciplinary university, with more than 18,000 staff and 51,000 students from over 150 different countries. UCL consistently demonstrates research power and impact at the highest level and is fortunate to educate students of impressive talent and ambition from around the world. The VECG group investigates fundamentals and applications that enrich human experience of digital content. The group's research spans capture, modelling and display of a multisensory world, and involves hardware, algorithms and human-centred approaches.
Travel fees between UCL and Inria will BE covered.
Mission confiée
Context :
This postdoctoral research focuses on the modelling and simulation of dense human crowds, i.e. crowds in which social and physical interactions between individuals are mixed. The study of the behaviour of dense crowds is an important issue in terms of crowd management and accident prevention. Simulation of dense crowds is an essential part of these studies, but modelling the physical interactions between individuals still poses many unexplored challenges. The proposed postdoctoral program aims to make significant progress in this direction, and more specifically, the research on dense crowds will spawn new classes of Artificial Intelligence models.
To explore this area, the VirtUs team has a unique set of field data that captures the behaviour of dense crowds as observed at music festivals. The dataset includes videos of the crowd at festivals, a few manually checked tracked trajectories of individuals in the crowd, as well as automatically tracked trajectories of a large number of people in the image. The dataset also includes full-body motion capture for equipped participants in the crowd. As a continuation of recent work on modelling dense crowds, this postdoc aims to exploit the existing dataset for modeling and simulation purposes.
Objectives
The main goal of the postdoc is to establish new approaches to crowd simulation that are capable of learning new crowd dynamics based on their video observation, and to establish new crowd analysis methods based on simulation to improve the understanding of dense crowd behaviours.
The main activity of the postdoc will BE
- To explore new crowd data representations for machine learning approaches to crowd simulation
- To explore new models for data-driven crowd simulation
- To explore new metrics for the evaluation of crowd simulation and comparison with real-world data.
The postdoc is open in terms of approaches and paradigms for crowd simulation, including trajectory prediction using generative models, or imitation of crowd behaviour using reinforcement learning approaches. Candidates may establish their own approach in discussion with the management team.
Outcomes
We will aim to publish the results of this research in the best conferences and journals in the field, including IEEE CVPR or ACM SIGGRAPH, ACM TOG.
The postdoc opens up the possibility of applying for permanent research positions in the VirtUs team at the Inria centre at the University of Rennes.
