Toward a Multimodal Photogrammetric Acquisition and Processing Methodology for Monitoring Conservation and Restoration Studies
(The Eurographics Association, 2016)
Close-range photogrammetry is nowadays a common technique applied to acquire 3D data on Cultural Heritage (CH) artifacts. Image-based modeling are indeed providing useful resources for the documentation and the conservation ...
Probabilistic Marching Cubes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper we revisit the computation and visualization of equivalents to isocontours in uncertain scalar fields. We model uncertainty by discrete random fields and, in contrast to previous methods, also take arbitrary ...
Practical Real-Time Lens-Flare Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a practical real-time approach for rendering lens-flare effects. While previous work employed costly ray tracing or complex polynomial expressions, we present a coarser, but also significantly faster solution. ...
Retailoring Box Splines to Lattices for Highly Isotropic Volume Representations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
3D box splines are defined by convolving a 1D box function with itself along different directions. In volume visualization, box splines are mainly used as reconstruction kernels that are easy to adapt to various sampling ...
2D/3D Semantic Annotation of Spatialized Images for the Documentation and Analysis of Cultural Heritage
(The Eurographics Association, 2016)
The introduction of digital technologies in the documentation methods for cultural heritage has helped to design new tools for the acquisition and management of information collected for multidisciplinary studies. These ...
Illustrative PET/CT Visualisation of SIRT-Treated Lung Metastases
(The Eurographics Association, 2016)
We present an illustrative rendering pipeline which combines anatomical information from CT scans with functional information from PET scans. To treat lung metastases with Selective Internal Radiation Therapies (SIRTs), ...
Computational Models for the Analysis and Synthesis of Graffiti Tag Strokes
(The Eurographics Association, 2015)
In this paper we describe a system aimed at the generation and analysis of graffiti tags.We argue that the dynamics of the movement involved in generating tags is in large part - and at a higher degree with respect to many ...
Scalable Seams for Gigapixel Panoramas
(The Eurographics Association, 2013)
Gigapixel panoramas are an increasingly popular digital image application. They are often created as a mosaic of smaller images composited into a larger single image. The mosaic acquisition can occur over many hours causing ...
Low-Cost Real-Time 3D Reconstruction of Large-Scale Excavation Sites using an RGB-D Camera
(The Eurographics Association, 2014)
In this paper, we present an end-to-end pipeline for the online reconstruction of large-scale outdoor environments and tightly confined indoor spaces using a low-cost consumer-level hand-held RGB-D sensor. While scanning, ...
3D Geological Modeling using Sketches and Annotations from Geologic Maps
(ACM, 2014)
Constructing 3D geological models is a fundamental task in oil/gas exploration and production. A critical stage in the existing 3D geological modeling workflow is moving from a geological interpretation (usually 2D) to a ...
