  • A Volume Visualization Algorithm using a coherent Extended Weight Matrix 

    Tost Pardell, Daniela; Puig Puig, Anna; Navazo Álvaro, Isabel (1995-01)
    Article
    Restricted access - publisher's policy
    Direct cell-to-cell volume visualization algorithms, also called projective rendering methods, present the advantage of allowing semi-transparencies and, additionally, as they project all the samples, they avoid the ...
  • An Adaptive Cutaway with Volume Context Preservation 

    Grau Carrion, Sergi; Puig Puig, Anna (Springer Berlin / Heidelberg, 2009-11-26)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Knowledge expressiveness of scientific data is one of the most important visualization goals. However, current volume visualization systems require a lot of expertise from the final user. In this paper, we present a ...
  • Efficient complementary viewpoint selection in volume rendering 

    Grau Carrion, Sergi; Puig Puig, Anna; Escalera, Sergio; Salamó, Maria; Amoros, Oscar (2013)
    Conference report
    Open Access
    A major goal of visualization is to appropriately express knowledge of scientific data. Generally, gathering visual information contained in the volume data often requires a lot of expertise from the final user to setup ...
  • Intelligent interactive volume classification 

    Grau Carrion, Sergi; Puig Puig, Anna; Escalera, Sergio; Salamó, Maria (2013)
    Conference report
    Restricted access - publisher's policy
    This paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ...
  • Region-based illustrative visualization of multimodal datasets 

    Abellán Moreno, Pascual; Tost Pardell, Daniela; Grau Carrion, Sergi; Puig Puig, Anna (2013-06-01)
    Article
    Restricted access - publisher's policy
    We present as novel method for the exploration of multiple overlapping volumes that provides flexibility to merge data in different ways in different regions. In each region, either one of the modalities is rendered alone ...
  • Time-varying volume visualization 

    Ayala Vallespí, M. Dolors; Campos Miralles, Jordi; Ferré, Maria; Grau Carrion, Sergi; Puig Puig, Anna; Tost Pardell, Daniela (2005-07-22)
    External research report
    Open Access
    Volume rendering is a very active research field in Computer Graphics because of its wide range of applications in various sciences, from medicine to flow mechanics. In this report, we survey a state-of-the-art on time-varying ...
