Enhancement of Heritage Experiences: the Middle Ages. Digital Layered Models of Architecture and Mural Paintings over Time
Contact: Andújar, Carlos
Financing institution: JPICH-Conservation, Protection and Use (EC) - PCI (Ministerio de Ciencia e Innovación)
Period: 01-09-2020 / 31-08-2023
Code: PCI2020-111979, JPICH-0127
The project aims to obtain virtual reconstructions of medieval artistic heritage - architecture with mural paintings- that are as close as possible to the original at different times, incorporating historical-artistic knowledge and the diachronic perspective of heritage, as an instrument for researchers, restorers and heritage curators and to improve the visitor's perceptions and experiences. In the digital models elaborated we intend to develop, as concrete objectives: 1. The understanding of architectural complexity, which is usually regularized geometrically. The collaboration of architects reveals the enormous interest of multidisciplinary dialogue in order to reach a real understanding of the construction of the building and its structural “anomalies". 2. Solving chromatic problems. The different restoration criteria followed over the years have resulted in notable differences in the current chromatic perception, sometimes of different fragments of the same ensemble. The analysis of pigments, the arrangement of the pictorial layers and the successive restorations suffered, with the help of conservation and restoration technicians, will allow us to digitally specify the original colouring of the paintings. 3. Raise and propose the resolution of lighting problems. To date, trials have been carried out for the restitution of these problems in digital models based on the analysis of natural lighting, which we intend to improve. We also propose to deal with artificial lighting by chandeliers or oil lamps, which produced effects of painting vibration at the moment when, for liturgical reasons, the images “acted". 4. To approach digitally the different perspectives of the medieval building and its paintings according to the categories of users. The laity did not have the same visual access as the clergy to the most decorated parts of the church; the iconographic programs did not have a universal addressee.

In this project, we focus on dealing with large models stemming mainly from two fields: life sciences and urban modeling. In life sciences we address three distinct sources of information: medical imaging devices (in the context of specific diagnostic problems and for training), molecular simulations in pharmacology, and biomechanical data. Concerning urban modeling, we focus on the generation of plausible models (geometric models, simulation of crowd behaviors, and of the decay due to natural processes) from the raw data. The data-capture systems in use in these applications (for example digital cartography or LIDAR scanners) provide models with incomplete information, or with not good enough quality for the applications we envision in engineering, architecture or smart cities. The general objectives of this project center on visualization, modeling urban environments, interaction and simulation of natural phenomena and the behavior of people and crowds. Despite the transversal nature of the proposed work, the specific objectives are conceived to facilitate the development of 3D applications meant to improve the quality of life of the people, both in their health (support for clinical diagnosis, simulations in sports biomechanics, design of new digs) and in their immediate surroundings (crowd behavior simulation, sustainable urban design, cultural heritage, energy efficiency analysis).

The understanding and simulation of the temporal evolution of urban environments is crucial not only for historical studies, but also for urban planning in modern cities. This proposal presents urbanEvolution, a project that aims to develop the first techniques ever for a user-controlled, automatic study of the evolution of buildings and whole cities over time. This study is expected to be done through the definition of urban states, which are procedural snapshots of the structure of an architectural or urban element; and operators, which produce discrete evolutions in these states into new ones reflecting the changes over time.

High-Performance Multi-Projector CAVE System
Contact: Brunet, Pere
Financing institution: ViRVIG
Period: 01-02-2009 / 30-04-2013
The goal of this project has been the design and construction of a novel, four wall multi- projector CAVE VR system which is powered by 40 off-the-shelf projectors controlled by 12 PCs. It operates in passive stereo, providing high brightness at 2000 x 2000 pixel resolution on each of the 4 walls. We have achieved high resolution while significantly reducing the cost and increasing versatility: the system works with any mix of a wide range of projector models that can be substituted at any moment for more modern or cheaper ones. The uniformity of the final image is achieved using a specially designed self-calibration software which adapts each of the 40 projectors and guarantees concordance and continuity. The system includes a gesture-based interaction approach based on a clever combination of skeletal data from multiple Kinect sensors. Interaction is intuitive and cableless.

Widespread uptake of HDR requires common interface standards. Currently they do not exist. There are isolated pockets of high-quality HDR endeavour across Europe, but not a co-ordinated approach. 2009 saw the appearance the first commercial HDR display and the world’s first HDR video camera. These European-led developments reinforce the timeliness of developing HDR standards and the special position Europe is in to lead the rapid acceleration of future HDR developments and market penetration. This COST Action (HDRi) assembles leading academic and industrial researchers and practitioners to propose a set of standards for the complete HDR pipeline and establish Europe firmly as the world leader in HDR.

High-Dynamic Range imaging for uncontrollable environments. 
Contact: Loscos, Céline and Martin, Ignacio
Financing institution: Ministerio Español de Educación y Ciencia.
Period: 01-04-2009 / 31-03-2011
We propose to explore a new approach to create high-dynamic range content with physically accurate radiance values from multi-exposed photographs. Accurate radiance values haven’t been so far ensured by previous methods but are crucial for research in illumination for mixed reality, image processing and photogrammetry. Our aim is to address a wide range of cameras and scene contents, including uncontrollable environments, such as exterior scenes with pedestrians or vegetation subject to wind. This involves solving ill-posed mathematical problems that are extremely difficult to solve, on uncontrollable data. Solutions should be as automatic and as free from user intervention as possible.

Presence: Research Encompassing Sensory Enhancement, Neuroscience, Cerebral-Computer Interfaces and Applications This Integrated Project will undertake a Research Programme that has as its major goal the delivery of presence in wide area distributed mixed reality environments. The environment will include a physical installation that people can visit both physically and virtually. The installation will be the embodiment of an artificial intelligent entity that understands and learns from its interaction with people. People who inhabit the installation will at any one time be physically there, virtually there but remote, or entirely virtual beings with their own goals and capabilities for interacting with one another and with embodiments of real people. Specific subclasses of the installation will be used for the construction of a number of application scenarios, such as a persistent virtual community that embodies the project itself. The core methodology will be to achieve this through the identification, understanding and exploitation of cerebral mechanisms for presence in conjunction with advances in the underlying technology for mixed reality display and interaction, with special attention to the interaction between people, and also between people and virtual people. Such cerebral mechanisms will be the basis for a core aspect of the IP which is the exploitation of brain-computer interfaces. Processes within the environments adapt and correlate with the behaviour and state of people, and in addition people are able to effect changes within the environment through thought as well as through motor actions.
