  • Biharmonic fields and mesh completion 

    Argudo Medrano, Óscar; Brunet Crosa, Pere; Chica Calaf, Antonio; Vinacua Pla, Álvaro (2015-11)
    Article
    Open Access
    We discuss bi-harmonic fields which approximate signed distance fields. We conclude that the bi-harmonic field approximation can be a powerful tool for mesh completion in general and complex cases. We present an adaptive, ...
  • Coherent multi-layer landscape synthesis 

    Argudo Medrano, Óscar; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio; Guerin, Eric (Springer, 2017-05-08)
    Article
    Open Access
    We present an efficient method for generating coherent multi-layer landscapes. We use a dictionary built from exemplars to synthesize high-resolution fully featured terrains from input low-resolution elevation data. Our ...

    Argudo Medrano, Óscar (Universitat Politècnica de Catalunya. Biblioteca Rector Gabriel Ferraté, 2018-06-19)
    Lecture
    Open Access
  • Il·luminació global d'entorns urbans 

    Argudo Medrano, Óscar (Universitat Politècnica de Catalunya, 2011-06-22)
    Master thesis (pre-Bologna period)
    Open Access
    Català: Aquest projecte té com objectiu principal la visualització realista, fent servir il luminació global, d entorns urbans, és a dir, models de ciutats. A més a més, es vol que aquesta sigui prou ràpida per permetre ...
  • Interactive inspection of complex multi-object industrial assemblies 

    Argudo Medrano, Óscar; Besora Vilardaga, Isaac; Brunet Crosa, Pere; Creus López, Carles; Hermosilla Casajús, Pedro; Navazo Álvaro, Isabel; Vinacua Pla, Álvaro (2016-10-01)
    Article
    Open Access
    The use of virtual prototypes and digital models containing thousands of individual objects is commonplace in complex industrial applications like the cooperative design of huge ships. Designers are interested in selecting ...
  • Plausible reconstruction ans rendering of semi-procedural landscapes 

    Argudo Medrano, Óscar (Universitat Politècnica de Catalunya, 2014-09-10)
    Master thesis
    Open Access
    We present a new method for the reconstruction of tree crowns from a single photograph, as well as an efficient representation to render them. The obtained model is used in our terrain viewer application to navigate through ...
  • Realistic reconstruction and rendering of detailed 3D scenarios from multiple data sources 

    Argudo Medrano, Óscar (Universitat Politècnica de Catalunya, 2018-07-19)
    Doctoral thesis
    Open Access
    During the last years, we have witnessed significant improvements in digital terrain modeling, mainly through photogrammetric techniques based on satellite and aerial photography, as well as laser scanning. These techniques ...
  • Segmentation of aerial images for plausible detail synthesis 

    Argudo Medrano, Óscar; Comino Trinidad, Marc; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio; Lumbreras, Felipe (2018-04-01)
    Part of book or chapter of book
    Open Access
    The visual enrichment of digital terrain models with plausible synthetic detail requires the segmentation of aerial images into a suitable collection of categories. In this paper we present a complete pipeline for segmenting ...
  • Single-picture reconstruction and rendering of trees for plausible vegetation synthesis 

    Argudo Medrano, Óscar; Chica Calaf, Antonio; Andújar Gran, Carlos Antonio (2016-06-01)
    Article
    Open Access
    State-of-the-art approaches for tree reconstruction either put limiting constraints on the input side (requiring multiple photographs, a scanned point cloud or intensive user input) or provide a representation only suitable ...
  • 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 ...
  • Tree variations 

    Argudo Medrano, Óscar; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio (2017)
    Conference report
    Open Access
    The cost-effective generation of realistic vegetation is still a challenging topic in computer graphics. The simplest representation of a tree consists of a single texture-mapped billboard. Although a tree billboard does ...
