Fast and Robust Semi-Automatic Registration of Photographs to 3D Geometry
(The Eurographics Association, 2011)
We present a simple, fast and robust technique for semi-automatic 2D-3D registration capable to align a large set of unordered images to a massive point cloud with minimal human effort. Our method converts the hard to solve ...
Real-time Rendering of Massive Unstructured Raw Point Clouds using Screen-space Operators
(The Eurographics Association, 2011)
Nowadays, 3D acquisition devices allow us to capture the geometry of huge Cultural Heritage (CH) sites, historical buildings and urban environments. We present a scalable real-time method to render this kind of models ...
Reconstructing and Exploring Massive Detailed Cityscapes
(The Eurographics Association, 2011)
We present a state-of-the-art system for obtaining and exploring large scale three-dimensional models of urban landscapes. A multimodal approach to reconstruction fuses cadastral information, laser range data, and oblique ...
An Automatic Word-spotting Framework for Medieval Manuscripts
(IEEE, 2015)
We present a completely automatic and scalable framework to perform query-by-example word-spotting on medieval manuscripts. Our system does not require any human intervention to produce a large amount of annotated training ...
Automated Color Clustering for Medieval Manuscript Analysis
(IEEE, 2015)
Given a color image of a medieval manuscript page, we propose a simple, yet efficient algorithm for automatically estimating the number of its color-based pixel groups, K. We formulate this estimation as a minimization ...
Split-Voxel: A Simple Discontinuity-Preserving Voxel Representation for Volume Rendering
(The Eurographics Association, 2010)
The most common representation of volumetric models is a regular grid of cubical voxels with one value each, from which a smooth scalar field is reconstructed. However, common real-world situations include cases in which ...
Multispectral RTI Analysis of Heterogeneous Artworks
(The Eurographics Association, 2017)
We propose a novel multi-spectral reflectance transformation imaging (MS-RTI) framework for the acquisition and direct analysis of the reflectance behavior of heterogeneous artworks. Starting from free-form acquisitions, ...
Adaptive Recommendations for Enhanced Non-linear Exploration of Annotated 3D Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel approach for letting casual viewers explore detailed 3D models integrated with structured spatially associated descriptive information organized in a graph. Each node associates a subset of the 3D ...
Geometric Analysis in Cultural Heritage
(The Eurographics Association, 2014)
We present a review of recent techniques for performing geometric analysis in cultural heritage applications, targeting the broad community of researchers and practitioners in cultural heritage computing. The problems ...
Improving the digitization of shape and color of 3D artworks in a cluttered environment
(The Eurographics Association, 2013)
We propose an approach for improving the digitization of shape and color of 3D artworks in a cluttered environment using 3D laser scanning and flash photography. In order to separate clutter from acquired material, ...
