Practical Free-form RTI Acquisition with Local Spot Lights
(The Eurographics Association, 2016)
We present an automated light calibration pipeline for free-form acquisition of shape and reflectance of objects using common off-the-shelf illuminators, such as LED lights, that can be placed arbitrarily close to the ...
A Survey of Geometric Analysis in Cultural Heritage
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a review of recent techniques for performing geometric analysis in cultural heritage (CH) applications. The survey is aimed at researchers in the areas of computer graphics, computer vision and CH computing, as ...
Guiding Lens-based Exploration using Annotation Graphs
(The Eurographics Association, 2021)
We introduce a novel approach for guiding users in the exploration of annotated 2D models using interactive visualization lenses. Information on the interesting areas of the model is encoded in an annotation graph generated ...
State-of-the-art in Multi-Light Image Collections for Surface Visualization and Analysis
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Multi-Light Image Collections (MLICs), i.e., stacks of photos of a scene acquired with a fixed viewpoint and a varying surface illumination, provide large amounts of visual and geometric information. In this survey, we ...
Automatic Geometric Calibration of Projector-based Light Field Displays
(The Eurographics Association, 2013)
We present a novel calibration method for continuous multiview (light field) projection-based displays using a single uncalibrated camera and four fiducial markers. Calibration starts from a simple parametric description ...
Recovering 3D Indoor Floor Plans by Exploiting Low-cost Spherical Photography
(The Eurographics Association, 2018)
We present a novel approach to automatically recover, from a small set of partially overlapping panoramic images, an indoor structure representation in terms of a 3D floor plan registered with a set of 3D environment maps. ...
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 ...
A Streaming Framework for Seamless Detailed Photo Blending on Massive Point Clouds
(The Eurographics Association, 2011)
We present an efficient scalable streaming technique for mapping highly detailed color information on extremely dense point clouds. Our method does not require meshing or extensive processing of the input model, works on ...
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 ...
