A 3D feature-based approach for mapping scaling effects on stone monuments
(Association for Computing Machinery (ACM), 2024-04-17)
Article
Open AccessWeathering effects caused by physical, chemical, or biological processes result in visible damages that alter the appearance of stones’ surfaces. Consequently, weathered stone monuments can offer a distorted perception of ... -
An annotation tool for digital restoration of wall paintings
(European Association for Computer Graphics (Eurographics), 2022)
Conference lecture
Open AccessAntique paintings are essential to study and understand our past. Paintings, and specifically mural paintings, are delicate artworks that are affected by multiple deterioration conditions. Weathering and human interventions ... -
Automated digital color restitution of mural paintings using minimal art historian input
(Elsevier, 2023-08)
Article
Open AccessDigital color restitution aims to digitally restore the original colors of a painting. Existing image editing applications can be used for this purpose, but they require a select-and-edit workflow and thus they do not scale ... -
Digital 3D models for medieval heritage: diachronic analysis and documentation of its architecture and paintings
(Springer, 2024-06-12)
Article
Open AccessIn this paper, we discuss the requirements and technical challenges within the EHEM project, Enhancement of Heritage Experiences: The Middle Ages, an ongoing research program for the acquisition, analysis, documentation, ... -
Digital layered models of architecture and mural paintings over time
(European Association for Computer Graphics (Eurographics), 2021)
Conference report
Open AccessThe European project Enhancement of Heritage Experiences: The Middle Ages. Digital Layered Models of Architecture and Mural Paintings over Time (EHEM) aims to obtain virtual reconstructions of medieval artistic heritage ... -
Digital reconstruction of partially lost altarpieces. The case of the Rosary's altarpiece of Sant Pere Màrtir de Manresa
(Association for Computing Machinery (ACM), 2024-05-15)
Article
Open AccessAn important challenge of Digital Cultural Heritage is to contribute to the recovery of artworks with their original shape and appearance. Many altarpieces, which are very relevant Christian art elements, have been damaged ... -
Digital reintegration of distributed mural paintings at different architectural phases: the case of St. Quirze de Pedret
(European Association for Computer Graphics (Eurographics), 2022)
Conference report
Open AccessSant Quirze de Pedret is a Romanesque church located in Cercs (Catalonia, Spain) at the foothills of the Pyrenees. Its walls harbored one of the most important examples of mural paintings in Catalan Romanesque Art. However, ... -
Digital Twins for medieval monuments: requirements from art historians and technical challenges for analysis and restoration
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessResearch on Visual Computing and Cultural Heritage naturally requires the involvement of multidisciplinary teams comprising art historians and technical experts. Despite the vast literature on digital 3D models in support ... -
Gain compensation across LIDAR scans
(2022-08)
Article
Open AccessHigh-end Terrestrial Lidar Scanners are often equipped with RGB cameras that are used to colorize the point samples. Some of these scanners produce panoramic HDR images by encompassing the information of multiple pictures ... -
Nightlighting
(Universitat Politècnica de Catalunya, 2012-09)
Master thesis
Open AccessGlobal illumination techniques have briefly been addressed to urban renderings. To the best of our knowledge, the algorithm we present in this master thesis is the fi rst one to compute nocturnal global illumination of a ... -
NightLighting: a nocturnal urban illumination approach
(European Association for Computer Graphics (Eurographics), 2013)
Conference report
Restricted access - publisher's policyReal time rendering of cities with realistic global illumination is still an open problem. In this paper we propose a two-step algorithm to simulate the nocturnal illumination of a city. The first step computes an approximate ... -
Real-time solar exposure simulation in complex cities
(John Wiley & sons, 2017-12)
Article
Open AccessIn urban design, estimating solar exposure on complex city models is crucial but existing solutions typically focus on simplified building models and are too demanding in terms of memory and computational time. In this ... -
