    • 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 ...
    • Depth map repairing for building reconstruction 

      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 ...
    • Detail synthesis on terrain models using aerial images 

      Argudo Medrano, Óscar (Universitat Politècnica de Catalunya. Biblioteca Rector Gabriel Ferraté, 2018-06-19)

    • 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 ...
    • Image-based tree variations 

      Argudo Medrano, Óscar; Andújar Gran, Carlos Antonio; Chica Calaf, Antonio (2020-02)
      Article
      Open Access
      The automatic generation of realistic vegetation closely reproducing the appearance of specific plant species is still a challenging topic in computer graphics. In this paper, we present a new approach to generate new tree ...
    • 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
