    • A Complete solid model for surface rendering 

      Rodríguez Rojas, Jorge Ernesto; Ayala Vallespí, M. Dolors; Aguilera, Antonio (2003-02)
      Report de recerca
      Accés obert
      The Extreme Vertices Model (EVM) has been presented as a concise and complete model for representing orthogonal pseudo-polyhedra (OPP) in the solid modeling field. This model exploits the simplicity of its domain ...

    • Efficient computation of 3D skeletons by extreme vertex encoding 

      Rodríguez Rojas, Jorge Ernesto; Thomas, Federico; Ayala Vallespí, M. Dolors; Ros Giralt, Lluís (2003)
      Article
      Accés obert
      Many skeletonisation algorithms for discrete volumes have been proposed. Despite its simplicity, the one given here still has many theoretically favorable properties. Actually, it provides a connected surface skeleton that ...

    • Fast neighborhood operations for images and volume datasets 

      Rodríguez Rojas, Jorge Ernesto; Ayala Vallespí, M. Dolors (2003-02)
      Report de recerca
      Accés obert
      This paper presents a new approach to carry out erosion, dilation and connected component labeling. We use the Extreme Vertices Model (EVM), an orthogonal polyhedra representation, to describe binary images and ...

    • Representation and boundary extraction of a 3D digital image using the EVM model 

      Ayala Vallespí, M. Dolors; Aguilera Ramírez, Fernando Antonio; Rodríguez Rojas, Jorge Ernesto (2000-11)
      Report de recerca
      Accés obert
      In recent published papers we have presented the Extreme Vertices Model (EVM), a concise and complete model for representing orthogonal polyhedra. This model exploits the simplicity of its domain by allowing robust and ...

    • Técnicas de extracción de superfícies a partir de imágenes digitales 3D 

      Rodríguez Rojas, Jorge Ernesto (2000-10)
      Report de recerca
      Accés obert
      The boundary extraction from 3D data sets is a very important topic in scientific visualization. Several techniques have been published to generate surfaces from 3D digital images. However, the research efforts have ...

    • VolumeEVM: A new surface/volume integrated model 

      Rodríguez Rojas, Jorge Ernesto; Ayala Vallespí, M. Dolors (2003-07)
      Report de recerca
      Accés obert
      Volume visualization is a very active research area in the field of scien-tific visualization. The Extreme Vertices Model (EVM) has proven to be a complete intermediate model to visualize and manipulate volume data using ...
