- W2912905001 abstract "Overview: Recent years have witnessed a great increase in the interest in digitally capturing and representing world heritage sites for preservation and access. The UNESCO World Heritage Programme now has 851 listed sites, all considered as sites of outstanding cultural or natural importance to the common heritage of humanity. Of these, 660 sites are cultural sites, 166 are natural and 25 have mixed properties.But the concept of Heritage is much vaster than the tangible places around the Earth: there is the need to preserve not only the ancient documentation (manuscripts, photos, sound recordings), but also the intangible material which defines the diversified cultures in the world (orally transmitted stories, dances).Why are these preservation and digital access projects necessary? Capturing digital representations provides mechanisms for preservation, as well as access, and even scholarly study. Digital analysis and processing can also provide means for the restoration of important documentation.Even if we had not faced the challenge of preservation, we would still face a problem of accessibility. Most of these sites are out of reach to most people. A significant amount of archeological and art objects are carefully kept in museums cellars and are not displayed. Digital acquisition and display of Cultural Heritage, art, historical and archeological objects can assist preserving their original look, in case something happens to them. This can assist restoration efforts, and can significantly enhance the ability of people all over the work to view and enjoy them.Computer Vision, Graphics, and Multimedia research and practices have, and will continue, to play a central role in Cultural Heritage preservation efforts. The Second Workshop on eHeritage and Digital Art Preservation aims to bring together these researches as well as interdisciplinary researches that are related to these areas, in particular image and audio research, image and haptic (touch) research, as well as presentation of visual content over the world wide web and education. This workshop will follow the very successful First eHeritage Workshop which was held in conjunction with ICCV in Kyoto in 2009.While the range of issues and solutions covered by the selected papers is varied and diversified, we would like to focus on three main subjects which cover different aspects of the promising field of Digital Preservation.Acquisition and visualization of Heritage sites: the advancements in the technology for the acquisition of three-dimensional data have started a revolution in the way excavation documentation is acquired. A wide range of approaches, from the consolidated Photogrammetry to 3D Scanning and Dense Stereo Matching, lets researchers deal with very different conditions.Moreover, the improvements in the software for data manipulation has given the possibility to people working on the field, like the archaeologist and the art historian, to perform data acquisition without the need of extreme expertise.Nevertheless, it proved to be difficult to define guidelines for the collection of three-dimensional data, since each single case needs to define first the use of the acquired data (tourist visualization, numerical analysis, interpretation). Moreover, in most practical cases the acquisition campaign can be difficult, even to the point of forcing to discard some types of technologies due to physical or temporal constraints.Hence, in the context of Digital Preservation, any work which presents a case study where challenging artifacts were faced, or where different kinds of technologies or data are combined to obtain an accurate but usable 3D model can still be considered as a contribution to the community.In particular, the advent of robust and reliable techniques for the automatic reconstruction from images, and the development of new and flexible open source tools for data processing and visualization are opening new perspectives for the analysis, preservation and presentation of Heritage sites.Historic Material and Intangible Heritage: while the acquisition of the geometry and appearance of objects is a straight-forward application of technology for Cultural Heritage, the contribution to the scientific community can cover a much larger range of issues.One important application where digital technology can intervene is the restoration and preservation of historic material. Not only ancient manuscripts, but also more recent photo and film collections and sound recordings are an extremely valuable source to document and interpret the past.Image, video, and sound processing techniques can actively support the work of the restorers, and uncover valuable hidden information. Moreover, the digitalization of historic material helps with its preservation, and at the same time it permits the dissemination of the material to a larger audience through remote connections like the Web.An even more interesting challenge deals with the Intangible Heritage, which is everything related to tradition. Dance, feasts, tunes which underwent oral dissemination must be preserved in some way. Moreover, their analysis and comparison can help experts find connections between various traditions and support different points of view.These two types of material represent an extremely valuable input for the creation of new and more complex algorithms in the context not only of Multimedia, but also of Computer Vision and Computer Graphics.Interactive visualization and presentation of data. New technologies provide easy ways to acquire very large amount of data, or to find connections in heterogeneous material.But in most cases, the visualization of the data or of their connections is hard to overcome. In particular, 3D scanned objects tend to be quite complex, so that robust and custom solutions are needed for remote navigation.Also the integration of different kinds of data (3D models, images, text, web pages) must be performed in order to help easy navigation even by non-expert users.Moreover, an effort is needed to integrate robust methods for the semantic analysis and organization of the heterogeneous data collections.Finally, technology can greatly improve the experience of people attending exhibitions, exploring historical centers or willing to share their photos and materials in social networks or virtual communities.In particular, the last generation of mobile devices can receive and provide very complex types of data, so that the experience of the users can be greatly enriched.In conclusion, the eHeritage and Digital Preservation Workshop will be a promising venue to share ideas, show practical experiences and explore new directions of work.The exploitation of new technologies can greatly improve the work of people involved in Cultural Heritage, and the Multimedia community is called to make a big effort to make it a reality and not only a perspective. We hope that this Workshop will represent a step towards this direction." @default.
