    Multispectral RTI Analysis of Heterogeneous Artworks 

    Giachetti, Andrea; Ciortan, Irina Mihaela; Daffara, Claudia; Pintus, Ruggero; Gobbetti, Enrico (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, ...

    A Practical Reflectance Transformation Imaging Pipeline for Surface Characterization in Cultural Heritage 

    Ciortan, Irina Mihaela; Pintus, Ruggero; Marchioro, Giacomo; Daffara, Claudia; Giachetti, Andrea; Gobbetti, Enrico (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 ...

    Crack Detection in Single- and Multi-Light Images of Painted Surfaces using Convolutional Neural Networks 

    Dulecha, Tinsae Gebrechristos; Giachetti, Andrea; Pintus, Ruggero; Ciortan, Irina; Villanueva, Alberto Jaspe; Gobbetti, Enrico (The Eurographics Association, 2019)
    Cracks represent an imminent danger for painted surfaces that needs to be alerted before degenerating into more severe aging effects, such as color loss. Automatic detection of cracks from painted surfaces' images would ...

    Real-time Rendering of Massive Unstructured Raw Point Clouds using Screen-space Operators 

    Pintus, Ruggero; Gobbetti, Enrico; Agus, Marco (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 ...

    Automated Color Clustering for Medieval Manuscript Analysis 

    Yang, Ying; Pintus, Ruggero; Gobbetti, Enrico; Rushmeier, Holly (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 ...

    Web-based Multi-layered Exploration of Annotated Image-based Shape and Material Models 

    Villanueva, Alberto Jaspe; Pintus, Ruggero; Giachetti, Andrea; Gobbetti, Enrico (The Eurographics Association, 2019)
    We introduce a novel versatile approach for letting users explore detailed image-based shape and material models integrated with structured, spatially-associated descriptive information. We represent the objects of interest ...

    Fast and Robust Semi-Automatic Registration of Photographs to 3D Geometry 

    Pintus, Ruggero; Gobbetti, Enrico; Combet, Roberto (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 ...

    SynthPS: a Benchmark for Evaluation of Photometric Stereo Algorithms for Cultural Heritage Applications 

    Dulecha, Tinsae Gebrechristos; Pintus, Ruggero; Gobbetti, Enrico; Giachetti, Andrea (The Eurographics Association, 2020)
    Photometric Stereo (PS) is a technique for estimating surface normals from a collection of images captured from a fixed viewpoint and with variable lighting. Over the years, several methods have been proposed for the task, ...

    Interactive 3D Exploration of a Virtual Sculpture Collection: an Analysis of User Behavior in Museum Settings 

    Agus, Marco; Marton, Fabio; Bettio, Fabio; Gobbetti, Enrico (The Eurographics Association, 2016)
    We present a usage analysis of an interactive system for the exploration of highly detailed 3D models of a collection of protostoric mediterranean sculptures. In this system, after selecting the object of interest inside ...

    Reconstructing and Exploring Massive Detailed Cityscapes 

    Gobbetti, Enrico; Marton, Fabio; Benedetto, Marco Di; Ganovelli, Fabio; Bühler, Matthias; Schubiger, Simon; Specht, Matthias; Engels, Chris; Gool, Luc Van (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 ...
