      Automatic emotion recognition based on body movement analysis: A survey 

      Zacharatos, H.; Gatzoulis, C.; Chrysanthou, Yiorgos L. (2014)
      Humans are emotional beings, and their feelings influence how they perform and interact with computers. One of the most expressive modalities for humans is body posture and movement, which researchers have recently started ...

      Breaking the walls: Scene partitioning and portal creation 

      Lerner, A.; Chrysanthou, Yiorgos L.; Cohen-Or, D. (IEEE Computer Society, 2003)
      In this paper, we revisit the cells-and-portals visibility methods, originally developed for the special case of architectural interiors. We define an effectiveness measure for a cells-and-portals partitioning, and introduce ...

      A case study of a virtual audience in a reconstruction of an ancient Roman odeon in Aphrodisias 

      Cain, K.; Chrysanthou, Yiorgos L.; Niccolucci, F.; Silberman, N. (Association for Computing Machinery, Inc, 2005)
      The benefits of including virtual humans into cultural heritage reconstructions are twofold: the realism of architectural models is increased by populating them

      Computing Dynamic Changes to BSP Trees 

      Chrysanthou, Yiorgos L.; Slater, M. (1992)
      This paper investigates a new method for dynamically changing Binary Space Partition (BSP) trees. A BSP tree representation of a 3D polygonal scene provides an ideal data structure for rapidly performing the hidden surface ...

      Context-dependent crowd evaluation 

      Lerner, A.; Chrysanthou, Yiorgos L.; Shamir, A.; Cohen-Or, D. (2010)
      Many times, even if a crowd simulation looks good in general, there could be some specific individual behaviors which do not seem correct. Spotting such problems manually can become tedious, but ignoring them may harm the ...

      The CREATE project: Mixed reality for design, education, and cultural heritage with a constructivist approach 

      Loscos, C.; Widenfeld, H. R.; Roussou, M.; Meyer, A.; Tecchia, F.; Drettakis, George; Gallo, E.; Martinez, A. R.; Tsingos, N.; Chrysanthou, Yiorgos L.; Robert, L.; Bergamasco, M.; Dettori, A.; Soubra, S. (Institute of Electrical and Electronics Engineers Inc., 2003)
      The global scope of the CREATE project is to develop a mixed-reality framework that enables highly interactive real-time construction and manipulation of photo-realistic, virtual worlds based on real data sources. This ...

      Crest line extraction from point clouds 

      Stylianou, Georgios; Chrysanthou, Yiorgos L. (2005)
      We present a simple, automatic method for extracting feature curves, called crest lines, from point clouds. Crest lines are surface shape features having a mathematical background. Given an unstructured point cloud as ...

      Crowd self-organization, streaming and short path smoothing 

      Soteris, Stylianou; Chrysanthou, Yiorgos L. (2006)
      Pedestrians implicitly cooperate by forming lanes inside dense crowd in order to facilitate flow and prevent complete passage blocking. Our aim is to re-enforce this self-organization phenomenon in dense crowd for the ...

      Crowds by example 

      Lerner, A.; Chrysanthou, Yiorgos L.; Lischinski, D. (2007)
      We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...

      Data driven evaluation of crowds 

      Lerner, A.; Chrysanthou, Yiorgos L.; Shamir, A.; Cohen-Or, D. (2009)
      There are various techniques for simulating crowds, however, in most cases the quality of the simulation is measured by examining its "look-and- feel". Even if the aggregate movement of the crowd looks natural from afar, ...

      A Data-Driven Framework for Visual Crowd Analysis 

      Charalambous, Panayiotis; Karamouzas, I.; Guy, S. J.; Chrysanthou, Yiorgos L. (2014)
      We present a novel approach for analyzing the quality of multi-agent crowd simulation algorithms. Our approach is data-driven, taking as input a set of user-defined metrics and reference training data, either synthetic or ...

      A distributed visualization system for crowd simulations 

      Vigueras, G.; Orduña, J. M.; Lozano, M.; Chrysanthou, Yiorgos L. (2011)
      The visualization system of large-scale crowd simulations should scale up with both the number of visuals (views of the virtual world) and the number of agents displayed in each visual. Otherwise, we could have large scale ...
