  • A 3D virtual model for training in endoscopical repair of subcondylar fractures of the mandible 

    Hueto, J.A.; Díaz Iriberri, José; Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau; Raspall, G. (2008-09)
    Article
    Accés restringit per política de l'editorial
    Conventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited surgical field. Proximity of facial nerve, carotid ...
  • Adaptive cross-sections of anatomical models 

    Díaz Iriberri, José; Monclús Lahoya, Eva; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (North-Holland, 2012-09)
    Article
    Accés restringit per política de l'editorial
    Medical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ...
  • An optimal parallel algorithm for learning DFA 

    Balcázar Navarro, José Luis; Díaz Iriberri, José; Gavaldà Mestre, Ricard; Watanabe, O. (Universitat Politècnica de Catalunya. Departament de Llenguatges i Sistemes Informàtics, 1993-01-01)
    Report de recerca
    Accés obert
    In 1987, D. Angluin presented an algorithm that exactly learns regular languages represented by deterministic finite automata (dfa) from Membership and Equivalence queries. Furthermore, the algorithm is feasible in the ...
  • Cost-effective feature enhancement for volume datasets 

    Díaz Iriberri, José; Marco Gómez, Jordi; Vázquez Alcocer, Pere Pau (2010)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Volume models often show high complexity. Local details and overall shape may sometimes be difficult to perceive. Unsharp masking techniques improve the perception of those small features by increasing the local contrast. ...
  • Depth-enhanced maximum intensity projection 

    Díaz Iriberri, José; Vázquez Alcocer, Pere Pau (2010)
    Text en actes de congrés
    Accés obert
    The two most common methods for the visualization of volumetric data are Direct Volume Rendering (DVR) and Maximum Intensity Projection (MIP). Direct Volume Rendering is superior to MIP in providing a larger amount of ...
  • Enhanced perception in volume visualization 

    Díaz Iriberri, José (Universitat Politècnica de Catalunya, 2013-04-26)
    Tesi
    Accés obert
    Due to the nature of scientic data sets, the generation of convenient visualizations may be a difficult task, but crucial to correctly convey the relevant information of the data. When working with complex volume models, ...
  • Inspección Interactiva de Estructuras Anatómicas Tubulares 

    Díaz Iriberri, José (Universitat Politècnica de Catalunya, 2007-07-18)
    Projecte Final de Màster Oficial
    Accés obert
    El objetivo que se persigue con esta tesis es analizar y evaluar los diferentes sistemas de visualización de datos volumétricos utilizados para realizar inspecciones virtuales de estructuras tubulares, así como proponer ...
  • Perceptual effects of volumetric shading models in stereoscopic desktop-based environments 

    Díaz Iriberri, José; Ropinski, Timo; Navazo Álvaro, Isabel; Gobbetti, Enrico; Vázquez Alcocer, Pere Pau (2015)
    Comunicació de congrés
    Accés obert
    Throughout the years, many shading techniques have been developed to improve the conveying of information in Volume Visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ...
  • Relief impostor selection for large scale urban rendering 

    Andújar Gran, Carlos Antonio; Díaz Iriberri, José; Brunet Crosa, Pere (2008)
    Comunicació de congrés
    Accés obert
    Image-based rendering techniques are often the preferred choice to accelerate the exploration of massive outdoor models and complex human-made structures. In the last few years, relief mapping has been shown to be extremely ...
  • The Hardness of intervalizing four colored caterpillars 

    Serna Iglesias, María José; Díaz Iriberri, José; Álvarez Faura, M. del Carme (1998-07-02)
    Report de recerca
    Accés obert
    The problem of Intervalizing Colored Graphs (ICG) has received a lot of attention due to their use as a model for DNA physical mapping with ambiguous data. If k is the number of colors, the problem is known to be NP-Complete ...
  • The virtual magic lantern: an interaction metaphor for enhanced medical data inspection 

    Monclús Lahoya, Eva; Díaz Iriberri, José; Vázquez Alcocer, Pere Pau; Navazo Álvaro, Isabel (Association for Computing Machinery (ACM), 2009)
    Comunicació de congrés
    Accés obert
    In this paper we present the Virtual Magic Lantern (VML), an interaction tool tailored to facilitate volumetric data inspection. It behaves like a lantern whose virtual illumination cone provides the focal region which ...
  • The Virtual Magic Lantern: An interaction metaphor for enhanced medical data inspection 

    Monclús Lahoya, Eva; Díaz Iriberri, José; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (2010-03)
    Report de recerca
    Accés obert
    In Volume Rendering, it is difficult to simultaneously visualize interior and exterior structures. Several approaches have been developed to solve this problem, such as cut-away or exploded views. Nevertheless, in most ...
  • Vicinity Occlusion Maps: Enhanced Depth Perception of Volumetric Models 

    Díaz Iriberri, José; Yela Reneses, Héctor; Vázquez Alcocer, Pere Pau (2008)
    Comunicació de congrés
