Biharmonic fields and mesh completion
Argudo Medrano, Óscar; Brunet Crosa, Pere; Chica Calaf, Antonio; Vinacua Pla, Álvaro (2015-11)
Article
Accés obertWe 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
Accés obertWe 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

Digital reintegration of distributed mural paintings at different architectural phases: the case of St. Quirze de Pedret
Muñoz Pandiella, Imanol; Argudo Medrano, Óscar; Lorès Otzet, Immaculada; Font Comas, Joan; Àvila Casademont, Genís; Pueyo Sandez, Francesc Xavier; Andújar Gran, Carlos Antonio (European Association for Computer Graphics (Eurographics), 2022)
Text en actes de congrés
Accés obertSant Quirze de Pedret is a Romanesque church located in Cercs (Catalonia, Spain) at the foothills of the Pyrenees. Its walls harbored one of the most important examples of mural paintings in Catalan Romanesque Art. However, ... -
Gain compensation across LIDAR scans
Muñoz Pandiella, Imanol; Comino Trinidad, Marc; Andújar Gran, Carlos Antonio; Argudo Medrano, Óscar; Bosch Geli, Carles; Chica Calaf, Antonio; Martínez Navarro, Beatriz (2022-08)
Article
Accés obertHigh-end Terrestrial Lidar Scanners are often equipped with RGB cameras that are used to colorize the point samples. Some of these scanners produce panoramic HDR images by encompassing the information of multiple pictures ... -
Il·luminació global d'entorns urbans
Argudo Medrano, Óscar (Universitat Politècnica de Catalunya, 2011-06-22)
Projecte/Treball Final de Carrera
Accés obertCatalà: 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
Accés obertThe 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
Accés obertThe 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)
Projecte Final de Màster Oficial
Accés obertWe 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)
Tesi
Accés obertDuring 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)
Capítol de llibre
Accés obertThe 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
Accés obertState-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 ... -
