    Andújar Gran, Carlos Antonio; Argudo Medrano, Óscar; Besora Vilardaga, Isaac; Brunet Crossa, Pere; Chica Calaf, Antonio; Comino Trinidad, Marc (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    Structure-from-motion along with multi-view stereo techniques jointly allow for the inexpensive scanning of 3D objects (e.g. buildings) using just a collection of images taken from commodity cameras. Despite major advances ...
  • Top-down model fitting for hand pose recovery in sequences of depth images 

    Madadi, Meysam; Escalera, Sergio; Carruesco Llorens, Àlex; Andújar Gran, Carlos Antonio; Baró, Xavier; Gonzàlez, Jordi (2018-11)
    Article

    State-of-the-art approaches on hand pose estimation from depth images have reported promising results under quite controlled considerations. In this paper we propose a two-step pipeline for recovering the hand pose from a ...
  • VR-assisted architectural design in a heritage site: the Sagrada Família case study 

    Andújar Gran, Carlos Antonio; Brunet Crossa, Pere; Buxareu, Jeronimo; Fons Sánchez, Joan; Laguarda, Narcis; Pascual, Jordi; Pelechano Gómez, Núria (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    Virtual Reality (VR) simulations have long been proposed to allow users to explore both yet-to-built buildings in architectural design, and ancient, remote or disappeared buildings in cultural heritage. In this paper we ...
  • Users’ locomotor behavior in collaborative virtual reality 

    Ríos Jérez, Alejandro; Palomar Soler, Marc; Pelechano Gómez, Núria (Association for Computing Machinery (ACM), 2018)
    Conference report
    Restricted access - publisher's policy
    This paper presents a virtual reality experiment in which two participants share both the virtual and the physical space while performing a collaborative task. We are interested in studying what are the differences in human ...
  • Monte Carlo convolution for learning on non-uniformly sampled point clouds 

    Hermosilla Casajús, Pedro; Ristchel, Tobias; Vázquez Alcocer, Pere Pau; Vinacua Pla, Álvaro; Ropinski, Timo (2018-11)
    Article
    Open Access
    Deep learning systems extensively use convolution operations to process input data. Though convolution is clearly defined for structured data such as 2D images or 3D volumes, this is not true for other data types such as ...
  • Rendering and interacting with volume models in inmmersive environments 

    Fons, Joan; Monclús Lahoya, Eva; Vázquez Alcocer, Pere Pau; Navazo Álvaro, Isabel (European Association for Computer Graphics (Eurographics), 2018)
    Conference report
    Open Access
    The recent advances in VR headsets, such as the Oculus Rift or HTC Vive, at affordable prices offering a high resolution display, has empowered the development of immersive VR applications. Unfortunately, the rendering ...
  • Quasi-automatic colon segmentation on T2-MRI images with low user effort 

    Orellana, Bernat; Monclús Lahoya, Eva; Brunet Crossa, Pere; Navazo Álvaro, Isabel; Bendezú García, Álvaro; Azpiroz Vidaur, Fernando (Springer, 2018)
    Conference report
    Restricted access - publisher's policy
    About 50% of the patients consulting a gastroenterology clinic report symptoms without detectable cause. Clinical researchers are interested in analyzing the volumetric evolution of colon segments under the effect of ...
  • Sensor-aware normal estimation for point clouds from 3D range scans 

    Comino Trinidad, Marc; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Brunet Crossa, Pere (2018)
    Article
    Restricted access - publisher's policy
    Normal vectors are essential for many point cloud operations, including segmentation, reconstruction and rendering. The robust estimation of normal vectors from 3D range scans is a challenging task due to undersampling and ...
  • Terrain super-resolution through aerial imagery and fully convolutional networks 

    Argudo Medrano, Óscar; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (2018-05-22)
    Article
    Restricted access - publisher's policy
    Despite recent advances in surveying techniques, publicly available Digital Elevation Models (DEMs) of terrains are low-resolution except for selected places on Earth. In this paper we present a new method to turn ...
  • Introducing semi-open learning/teaching into fundamental programming subjects 

    Xhafa Xhafa, Fatos; Marco Gómez, Jordi; Vázquez Alcocer, Pere Pau (Universitat de Barcelona. Edicions i Publicacions, 2006)
    Conference report
    Open Access
    Due to the development of Internet applications, semi-open learning is increasingly being introduced into traditional face-to-face learning and teaching. In several engineering degrees many subjects are developed using a ...
  • Visualization of large molecular trajectories 

    Duran Rosich, David; Hermosilla Casajús, Pedro; Ropinski, Timo; Kozliková, Barbora; Vinacua Pla, Álvaro; Vázquez Alcocer, Pere Pau (2018-09-06)
    Article
    Open Access
    The analysis of protein-ligand interactions is a time-intensive task. Researchers have to analyze multiple physico-chemical properties of the protein at once and combine them to derive conclusions about the protein-ligand ...
  • Improving perception accuracy in bar charts with internal contrast and framing enhancements
