Enhanced perception in volume visualization
Díaz Iriberri, José (Universitat Politècnica de Catalunya, 2013-04-26)
Tesi
Accés obertDue to the nature of scientic data sets, the generation of convenient visualizations may be a difficult task, but crucial to correctly convey the relevant information of the data. When working with complex volume models, ... -
Improving perception accuracy in bar charts with internal contrast and framing enhancements
Díaz Iriberri, José; Meruvia Pastor, Oscar; Vázquez Alcocer, Pere Pau (Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertBar charts are among the most commonly used visualization graphs. Their main goal is to communicate quantities that can be visually compared. Since they are easy to produce and interpret, they are found in any situation ... -
Inspección Interactiva de Estructuras Anatómicas Tubulares
Díaz Iriberri, José (Universitat Politècnica de Catalunya, 2007-07-18)
Projecte Final de Màster Oficial
Accés obertEl objetivo que se persigue con esta tesis es analizar y evaluar los diferentes sistemas de visualización de datos volumétricos utilizados para realizar inspecciones virtuales de estructuras tubulares, así como proponer ... -
Interactive framework for the visual exploration of colonic data
Males, Jan; Monclús Lahoya, Eva; Díaz Iriberri, José; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (2020-10)
Article
Accés obertComputerized Tomography (CT) and, more recently, Magnetic Resonance Imaging (MRI) have become the state-of-the art techniques for morpho-volumetric analysis of abdominal cavities. Due to its constant motility, the colon ... -
Perceptual effects of volumetric shading models in stereoscopic desktop-based environments
Díaz Iriberri, José; Ropinski, Timo; Navazo Álvaro, Isabel; Gobbetti, Enrico; Vázquez Alcocer, Pere Pau (2015)
Comunicació de congrés
Accés obertThroughout the years, many shading techniques have been developed to improve the conveying of information in Volume Visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ... -
Relief impostor selection for large scale urban rendering
Andújar Gran, Carlos Antonio; Díaz Iriberri, José; Brunet Crosa, Pere (2008)
Comunicació de congrés
Accés obertImage-based rendering techniques are often the preferred choice to accelerate the exploration of massive outdoor models and complex human-made structures. In the last few years, relief mapping has been shown to be extremely ... -
The Hardness of intervalizing four colored caterpillars
Serna Iglesias, María José; Díaz Iriberri, José; Álvarez Faura, M. del Carme (1998-07-02)
Report de recerca
Accés obertThe problem of Intervalizing Colored Graphs (ICG) has received a lot of attention due to their use as a model for DNA physical mapping with ambiguous data. If k is the number of colors, the problem is known to be NP-Complete ... -
The Virtual magic lantern: an interaction metaphor for enhanced medical data inspection
Monclús Lahoya, Eva; Díaz Iriberri, José; Navazo Álvaro, Isabel; Vázquez Alcocer, Pere Pau (2010-03)
Report de recerca
Accés obertIn Volume Rendering, it is difficult to simultaneously visualize interior and exterior structures. Several approaches have been developed to solve this problem, such as cut-away or exploded views. Nevertheless, in most ... -
The virtual magic lantern: an interaction metaphor for enhanced medical data inspection
Monclús Lahoya, Eva; Díaz Iriberri, José; Vázquez Alcocer, Pere Pau; Navazo Álvaro, Isabel (Association for Computing Machinery (ACM), 2009)
Comunicació de congrés
Accés obertIn this paper we present the Virtual Magic Lantern (VML), an interaction tool tailored to facilitate volumetric data inspection. It behaves like a lantern whose virtual illumination cone provides the focal region which ... -
TourVis: narrative visualization of multi-stage bicycle races
Díaz Iriberri, José; Fort Masdevall, Marta; Vázquez Alcocer, Pere Pau (2021)
Article
Accés obertThere are many multiple-stage racing competitions in various sports such as swimming, running, or cycling. The wide availability of affordable tracking devices facilitates monitoring the position along with the race of all ... -
Vicinity Occlusion Maps: Enhanced Depth Perception of Volumetric Models
Díaz Iriberri, José; Yela Reneses, Héctor; Vázquez Alcocer, Pere Pau (2008)
Comunicació de congrés
Accés obertVolume models often show high depth complexity. This poses di±culties to the observer in judging the spatial relationships accurately. Illustrators usually use certain techniques such as halos or edge darkening in order ...
