A 3D virtual model for training in endoscopical repair of subcondylar fractures of the mandible
(2008-09)
Article
Restricted access - publisher's policyConventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited surgical field. Proximity of facial nerve, carotid ... -
A Web-based application for the visual exploration of colon morphology data
(European Association for Computer Graphics (Eurographics), 2019)
Conference report
Open AccessThe colon is an organ whose constant motility poses difficulties to its analysis. Although morphological data can be successfully extracted from Computational Tomography, its radiative nature makes it only indicated for ... -
Adaptive cross-sections of anatomical models
(North-Holland, 2012-09)
Article
Restricted access - publisher's policyMedical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ... -
An experimental study on the effects of shading in 3D perception of volumetric models
(Springer, 2017-01)
Article
Restricted access - publisher's policyThroughout 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 ... -
Cost-effective feature enhancement for volume datasets
(2010)
Conference report
Restricted access - publisher's policyVolume models often show high complexity. Local details and overall shape may sometimes be difficult to perceive. Unsharp masking techniques improve the perception of those small features by increasing the local contrast. ... -
Depth-enhanced maximum intensity projection
(2010)
Conference report
Open AccessThe two most common methods for the visualization of volumetric data are Direct Volume Rendering (DVR) and Maximum Intensity Projection (MIP). Direct Volume Rendering is superior to MIP in providing a larger amount of ... -
Enhanced perception in volume visualization
(Universitat Politècnica de Catalunya, 2013-04-26)
Doctoral thesis
Open AccessDue 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
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Open AccessBar 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
(Universitat Politècnica de Catalunya, 2007-07-18)
Master thesis
Open AccessEl 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
(2020-10)
Article
Open AccessComputerized 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
(2015)
Conference lecture
Open AccessThroughout 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
(2008)
Conference lecture
Open AccessImage-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
(1998-07-02)
Research report
Open AccessThe 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
(Association for Computing Machinery (ACM), 2009)
Conference lecture
Open AccessIn 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 ... -
The Virtual magic lantern: an interaction metaphor for enhanced medical data inspection
(2010-03)
Research report
Open AccessIn 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 ... -
TourVis: narrative visualization of multi-stage bicycle races
(2021)
Article
Open AccessThere 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
(2008)
Conference lecture
Open AccessVolume 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 ...
