  • Coupling camera-tracked humans with a simulated virtual crowd 

    Rivalcoba, Jorge Ivan; De Gyves, Oriam; Rudomin, Isaac; Pelechano Gómez, Núria (SciTePress, 2014)
    Conference report
    Open Access
    Our objective with this paper is to show how we can couple a group of real people and a simulated crowd of virtual humans. We attach group behaviors to the simulated humans to get a plausible reaction to real people. We ...
  • CAVAST: The crowd animation, visualization, and simulation testbed 

    Beacco Porres, Alejandro; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2014)
    Conference report

    Simulation, animation and rendering of crowds has become an important part of real-time applications such as videogames. Virtual environments achieve higher realism when being populated by virtual crowds as opposed to ...
  • NightLighting: a nocturnal urban illumination approach 

    Muñoz Pandiella, Imanol; Andújar Gran, Carlos Antonio; Patow, Gustavo (European Association for Computer Graphics (Eurographics), 2013)
    Conference report

    Real time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ...
  • A generalized exact arbitrary clearance technique for navigation meshes 

    Oliva Martínez, Ramon; Pelechano Gómez, Núria (ACM, 2013)
    Conference report
    Open Access
    There are two frequent artifacts in crowd simulation, the first one appears when all agents attempt to traverse the navigation mesh sharing the same way point over portals, increasing the probability of collision against ...
  • Introductory graphics for very diverse audiences 

    Fairén González, Marta; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2013)
    Conference report
    Restricted access - publisher's policy
    This paper presents our first experience teaching WebGL in a master’s degree for a class of students with very different backgrounds. The main challenge was to prepare a course that would be engaging for students with ...
  • Structural stability of planar bimodal linear systems 

    Ferrer Llop, Josep; Peña Carrera, Marta; Susín Sánchez, Antonio (American Institute of Physics (AIP), 2013)
    Conference report
    Open Access
    We consider bimodal linear dynamical systems consisting of two linear dynamics acting on each side of a given hyperplane, assuming continuity along the separating hyperplane. Focusing in the planar case, we describe which ...
  • Multi-domain real-time planning in dynamic environments 

    Kapadia, Mubbasir; Beacco Porres, Alejandro; Garcia, Francisco; Reddy, Vivek; Pelechano Gómez, Núria; Badler, Norman I. (2013)
    Conference lecture

    This paper presents a real-time planning framework for multi-character navigation that enables the use of multiple heterogeneous problem domains of differing complexities for navigation in large, complex, dynamic virtual ...
  • Full high-dynamic range images for dynamic scenes 

    Ramírez Orozco, Raissel; Martín, Ignacio; Loscos, Céline; Vázquez Alcocer, Pere Pau (2012)
    Conference report
    Open Access
    The limited dynamic range of digital images can be extended by composing photographs of the same scene taken with the same camera at the same view point at di erent exposure times. This is a standard procedure for static ...
  • Accurate multi-modal image registration using compression 

    Vázquez Alcocer, Pere Pau; Marco Gómez, Jordi (IADIS Press, 2011)
    Conference report
    Restricted access - publisher's policy
    Image registration is an important task in medicine, especially when images have been acquired by different scanner/sensor types, since they provide information on different body structures (bones, muscles, vessels...). ...
  • Biomechanical validation of upper-body and lower-body joint movements of kinect motion capture data for rehabilitation treatments 

    Fernández-Baena, Adso; Susín Sánchez, Antonio; Lligadas, Xavier (IEEE Computer Society Publications, 2012)
    Conference report
    Open Access
    ew and powerful hardware like Kinect introduces the possibility of changing biomechanics paradigm, usually based on expensive and complex equipment. Kinect is a markerless and cheap technology recently introduced ...
