Integrated documentation of cultural heritage is a necessary process that precedes any other task or procedure regarding sustainable conservation and management. In order for any new methodology for monument documentation to be effective and widely applicable, not only it needs to be harmonized with existing standards but also, most importantly, be able to cover the variety and the particularity of cultural heritage, applying the best possible organization and management of knowledge. This is achieved by selecting and integrating common criteria that formulate a dynamic archive, collecting and organizing all information on the monument, during its entire life-time and by upgrading the current documentation methodologies. The proposed integrated documentation protocols support the development of sustainable maintenance and preservation through knowledge management by incorporating and supplying with all necessary data regarding decision making on determining priorities of Cultural Heritage protection. |

Capturing knowledge about damages and failures of culture heritage objects is a complex task because of term ambiguity, knowledge incompleteness and variety. To tackle this complexity, the paper introduces a semantic web ontology that aims at modeling monument damage knowledge with significant contextual information, including monument identification, damage identification, risk assessment, dam-age diagnosis and remedial measures. The developed ontology is being tested in the MONDIS project as background knowledge for custom software tools for management of damage failure knowledge. During the course of the project it becomes a common model for linked-data-compliant knowledge-based system serving different stakeholders to model/retrieve/compare different cases of damage and successful interventions. |

Rich metadata is crucial for the documentation and retrieval of 3D datasets in cultural heritage. Generating metadata is expensive as it is a very time consuming semi-manual process. The exponential increase of digital assets requires novel approaches for the mass generation of metadata. We present an approach that is generic, minimizes user assistance, and is customizable for different metadata schemes and storage formats as it is based on generic forms. It scales well and was tested with a large database of digital CH objects. |

In the field of CH metric documentation management the development of GIS tools has radically improved the capability of handling complex geometric models and the quantity of the semantic values of spatial data. These improvements in GIS tools have been followed by the development of data models and data definition languages able to manage such a complexity through a set of open rules and vocabularies. We need to change the application-driven practice of the GIS to a common set of rules and frameworks through the adoption of open-standards and languages. The aim of this study is to showcase the results of the test of framework for the management of a 3D metric survey archive by means of CityGML standard. |

In the restoration planning process a curator evaluates the condition of a Cultural Heritage (CH) object and accordingly develops a set of hypotheses for improving it. This iterative process is complex, time consuming and requires many manual interventions. In this context, we propose interactive modeling techniques, based on subdivision surfaces, which can support the completion of CH objects toward restoration planning. The proposed technique starts with a scanned and incomplete object, represented by a triangle mesh, from which a subdivision surfaces can be generated. Based on the mixed representation, sketching techniques and modeling operations can be combined to extend and refine the subdivision surface, according to the curator’s hypothesis. Thus, curators without rigorous modeling experience can directly create and manipulate surfaces in a similar way as they would do it on a piece of paper. We present the capabilities of the proposed technique on two interesting CH objects. |

Cultural heritage protection demands targeted restoration actions in order to increase monuments’ lifetime. Such actions require the use of conservation materials (e.g., consolidation materials), which can increase the durability of historic materials. However, the performance of each material on the restoration phase significantly differs with respect to its type, chemical properties and the building substrate. In this paper, we propose a new decision support architecture able to face these obstacles. The system automatically recommends to the experts the most suitable consolidation material product, among the available ones in the market. Integrated protocols are exploited, computer vision tools and artificial intelligence systems via user’s feedback. The proposed architecture is evaluated using a semi-supervised learning methodology on the design of consolidation materials. |

Byzantine art is overwhelmed by a multitude of icons that portray sacred faces. However, a large number of icons of historical value are either partially or totally damaged and thus in need of undergoing conservation. The detection and assessment of damage in cultural heritage artifacts comprise an integral part of the conservation process. In this paper, a method that can be used for assessing the damage on faces appearing in Byzantine icons is presented. The main approach involves the estimation of the residuals obtained after the coding and reconstruction of face image regions using trained Principal Component Analysis texture models. The extracted residuals can be used as the basis for obtaining information about the amount of damage and the positions of the damaged regions. Due to the specific nature of Byzantine icons several variations of the basic approach are tested through a quantitative experimental evaluation so that the methods most suited to the specific application domain are identified. As part of the experimental evaluation, holistic as well as patch-decomposition techniques have been utilized in order to catch the global and local information of the images, respectively. According to the results it is possible to detect and localize with reasonable accuracy the damaged areas of faces appearing in Byzantine icons. |

Today mapping of alterations of cultural heritage buildings and estimation of their degradation patterns is still a difficult task for several reasons. On one hand, buildings suffer from degradation problems depending on physical and chemical factors, whose causes can be difficult to determine. On the other hand, at the level of data representation, graphic supports need to be defined for deterioration analysis and heterogeneous data manipulation. The goal of this research is to supply experts with a tool for scientific monitoring and decision support so to permit rational programming operations of restorations. This paper proposes an approach for digital documentation of conservation state of buildings (stone alteration, dating, material), permitting to display and cross-reference data related to degradations. This approach will be described through the study case of stones at Chambord Castle. |

Climate change have impacts on many sectors: land use, housing, transportation, public health, water supply and sanitation, solid waste, food security, and energy. This article presents the results of the project SECHURBA , financed by European funds, whose purpose was to examine the potential of environmental protection and sustainability in historic cities, documenting barriers and prospects of various historical communities with diversity in Europe. Critical objectives which were achieved, such as ‘Historic Community Climate Change Strategies', assessment tools, route maps to intervene in areas such culturally sensitive, are under implementation in historic urban areas in Popular Republic of China. Through the application to some typical towns and villages in the Chinese province of Zeijang the outcomes of SECHURBA will developed to outline a set of actions and tools that will call ‘Historic Cities Regeneration by Climate Change Strategies'. |

Cultural heritage and archaeological sites are exposed to the risk of fire and early warning is the only way to avoid losses and damages. The use of terrestrial systems, typically based on video cameras, is currently the most promising solution for advanced automatic wildfire surveillance and monitoring. Video cameras are sensitive in visible spectra and can be used either for flame or smoke detection. This paper presents and compares three video-based flame detection techniques, which were developed within the FIRESENSE EU research project. |
