Color Enhancement for Rapid Prototyping
(The Eurographics Association, 2008)
We propose to exploit the color capabilities of recent rapid prototyping hardware devices to enhance the visual appearance of reproduced objects. In particular, by carefully pre-computing surface shading, we are able to ...
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 ...
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 ...
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, ...
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, ...
A TaLISMAN: Automatic Text and LIne Segmentation of historical MANuscripts
(The Eurographics Association, 2014)
Historical and artistic handwritten books are valuable cultural heritage (CH) items, as they provide information about tangible and intangible cultural aspects from the past. Massive digitization projects have made these ...
A Practical Reflectance Transformation Imaging Pipeline for Surface Characterization in Cultural Heritage
(The Eurographics Association, 2016)
We present a practical acquisition and processing pipeline to characterize the surface structure of cultural heritage objects. Using a free-form Reflectance Transformation Imaging (RTI) approach, we acquire multiple digital ...
