  • Sciatic nerve movement in the deep gluteal space during hip rotations maneuvers 

    Balius Matas, Ramon; Pujol, Montse; Pérez Cuenca, Dolores; Susín Sánchez, Antonio; Corominas Macias, Héctor; Sala Blanch, Xavier (2021-01-01)
    Article
    Open Access
    We hypothesize that the sciatic nerve in the subgluteal space has a specific behavior during internal and external coxofemoral rotation and during isometric contraction of the internal and external rotator muscles of the ...
  • Sweep encoding: Serializing space subdivision schemes for optimal slicing 

    Comino Trinidad, Marc; Vinacua Pla, Álvaro; Carruesco Llorens, Àlex; Chica Calaf, Antonio; Brunet Crosa, Pere (Elsevier, 2022-05)
    Article
    Open Access
    Slicing a model (computing thin slices of a geometric or volumetric model with a sweeping plane) is necessary for several applications ranging from 3D printing to medical imaging. This paper introduces a technique designed ...
  • Towards a human-like approach to path finding 

    Rahmani, Vahid; Pelechano Gómez, Núria (Elsevier, 2022-02)
    Article
    Restricted access - publisher's policy
    Path finding for autonomous agents has been traditionally driven by finding optimal paths, typically by using A* search or any of its variants. When it comes to simulating virtual humanoids, traditional approaches rarely ...
  • Procedural crowd generation for semantically augmented virtual cities 

    Roglà Pujalt, Otger; Patow, Gustavo Ariel; Pelechano Gómez, Núria (2021-10)
    Article

    Díaz Iriberri, José; Fort Masdevall, Marta; Vázquez Alcocer, Pere Pau (2021)
    Article
    Open Access
    There are many multiple-stage racing competitions in various sports such as swimming, running, or cycling. The wide availability of affordable tracking devices facilitates monitoring the position along with the race of all ...
  • Visual analysis of large-scale protein-ligand interaction data 

    Schatz, Karsten; Franco Moreno, Juan José; Schäfer, Marco; Rose, Alexander S.; Ferrario, Valerio; Pleiss, Jürgen; Vázquez Alcocer, Pere Pau; Ertl, Thomas; Krone, Michael (2021-09)
    Article
    Open Access
    When studying protein-ligand interactions, many different factors can influence the behaviour of the protein as well as the ligands. Molecular visualisation tools typically concentrate on the movement of single ligand ...
  • Enabling viewpoint learning through dynamic label generation 

    Schelling, Michael; Hermosilla Casajús, Pedro; Vázquez Alcocer, Pere Pau; Ropinski, Timo (2021-05)
    Article
    Open Access
    Optimal viewpoint prediction is an essential task in many computer graphics applications. Unfortunately, common viewpointqualities suffer from two major drawbacks: dependency on clean surface meshes, which are not always ...
  • Comparing navigation meshes: Theoretical analysis and practical metrics 

    van Toll, Wouter; Triesscheijn, Roy; Kallmann, Marcello; Oliva Martínez, Ramon; Pelechano Gómez, Núria; Pettré, Julien; Geraerts, Roland (2020-10)
    Article

    A navigation mesh is a representation of a 2D or 3D virtual environment that enables path planning and crowd simulation for walking characters. Various state-of-the-art navigation meshes exist, but there is no standardized ...
  • Estimating player positions from padel high-angle videos: Accuracy comparison of recent computer vision methods 

    Javadiha, Mohammadreza; Lacasa Claver, Enrique; Ric Díez, Angel; Andújar Gran, Carlos Antonio; Susín Sánchez, Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-12)
    Article
    Open Access
    The estimation of player positions is key for performance analysis in sport. In this paper, we focus on image-based, single-angle, player position estimation in padel. Unlike tennis, the primary camera view in professional ...
  • Variable selection in microbiome compositional data analysis 

    Susín Sánchez, Antonio; Calle, M. L.; Wang, Yiwen; Le Cao, Kim-Anh (2020-06-01)
    Article
    Open Access
    Though variable selection is one of the most relevant tasks in microbiome analysis, e.g. for the identification of microbial signatures, many studies still rely on methods that ignore the compositional nature of microbiome ...
