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 ...
Interactive 3D Exploration of a Virtual Sculpture Collection: an Analysis of User Behavior in Museum Settings
(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 ...
Web-based Multi-layered Exploration of Annotated Image-based Shape and Material Models
(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 ...
Crack Detection in Single- and Multi-Light Images of Painted Surfaces using Convolutional Neural Networks
(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 ...
Aging Prediction of Cultural Heritage Samples Based on Surface Microgeometry
(The Eurographics Association, 2018)
A critical and challenging aspect for the study of Cultural Heritage (CH) assets is related to the characterization of the materials that compose them and to the variation of these materials with time. In this paper, we ...
Interactive Exploration of Gigantic Point Clouds on Mobile Devices
(The Eurographics Association, 2012)
New embedded CPUs that sport powerful graphics chipsets have the potential to make complex 3D applications feasible on mobile devices. In this paper, we present a scalable architecture and its implementation for mobile ...
Objective and Subjective Evaluation of Virtual Relighting from Reflectance Transformation Imaging Data
(The Eurographics Association, 2018)
Reflectance Transformation Imaging (RTI) is widely used to produce relightable models from multi-light image collections. These models are used for a variety of tasks in the Cultural Heritage field. In this work, we carry ...
SynthPS: a Benchmark for Evaluation of Photometric Stereo Algorithms for Cultural Heritage Applications
(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, ...
