ITR/SY+AP: Acquisition, Representation, and Remote Visualization of Digital Artifacts

该项目的目标是研究和开发高质量、可扩展和可重构的数字图书馆馆藏采集和展示系统。我们将在波多黎各艺术博物馆获得新的数字藏品，并通过可伸缩和可重新配置的终端用户显示器提供对它们的访问。这些显示器将与远程模型服务器合作，以在当前网络条件下提供尽可能高的显示保真度。为了允许数字收藏的广泛获取和传播，需要在3D模型获取、内容交付和显示方面取得革命性的进展。为此，我们将专注于以下研究挑战：获取：我们将提供新的获取策略，旨在生成高质量的分层、基于图像的表示、3-D形状描述和多层数据。这些新战略将实现高效访问和最终用户的高分辨率显示。纹理、形状和元数据的混合表示。表示法：我们将以一种符合MPEG-4多媒体标准所提供的功能的方式对获取的集合进行编码。这种编码将保持数据的丰富性和保真度，同时实现集合随时间的访问、操作和演变的标准化。远程访问：我们将开发支持在异质网络环境中对数字馆藏进行分布式访问的新技术。这些技术将被设计来满足从非常高质量的本地显示和低延迟交互操作到通过广域、潜在低比特率链路的远程访问的各种频谱的访问需求。显示器：我们将为无法获得复杂而专门的技术支持和高成本硬件的机构和用户开发部署可伸缩平铺投影显示器的新技术。这些可扩展的显示系统可以由商用硬件组装而成，并提供自动、连续的校准和快速可重构。这项工作的动机源于对数字化藏品的高质量保存、访问和显示技术的需求。图书馆、博物馆和研究学者想要获取、操纵和提供对数字化文物的远程访问(和高清晰度展示)，需要具有成本效益的、非侵入性的、易于配置的方法来创建和查看高质量的藏品。新技术将在现实世界的图书馆藏品上进行评估，特别关注我们的合作机构波多黎各艺术博物馆的文物的保存和传播。在专家顾问的帮助下，我们将开发和部署一个原型系统，使用作为该项目一部分开发的技术进行采集和展示，他们将为我们的合作机构的这个项目做出重大贡献(见附函)。由此产生的数字档案将通过互联网向博物馆的赞助人以及世界各地更多的观众开放。我们相信这项研究将产生重大的直接、中期和长期影响。该项目的直接影响将是开发新的获取、获取和展示方法，这些方法将在波多黎各艺术博物馆部署和测试，使他们的部分藏品以以前不可能的形式提供。从中期来看，我们的新技术方法不仅对数字图书馆界有价值，而且对其他需要可配置大规模显示系统的研究、教学和商业领域(如教室、研究可视化中心、会议场所等)也有价值。从长远来看，我们相信这项拟议的工作有可能极大地影响人们查看和交互数据的方式，无论数据是历史人工制品的集合、复杂模拟的可视化表示、教室里的数据/插图等等。此外，我们方法的成本效益意味着它将被广泛的用户买得起。

The goal of this project is to research and develop high-quality, scalable, and reconfigurable acquisitionand display systems for digital library collections accessed via the Internet. We will acquire new digitalcollections at the Museo de Arte de Puerto Rico and provide access to them through end-user displaysthat are scalable and reconfigurable. These displays will cooperate with a remote model server toprovide the highest possible display fidelity under the current network conditions. In order to allowthe widespread acquisition and dissemination of digital collections, revolutionary advances in 3D modelacquistion, content delivery, and display are required. To thisend,we will focus on the following researchchallenges: Acquisition: we willprovide new acquisition strategies designed to produce high-quality layered,image-based representations, 3-D shape descriptions, and multi-layerd data. These new strategieswill enable efficient access and high-resolution end-user display. hybrid representation of texture,shape, and metadata. Representation: we will encode the acquired collection in a way that moves toward the featuresprovided in the MPEG-4 multimedia standard. This encoding will preserve the richness andfidelity of the data while achieving standardization for access, manipulation, and evolution ofcollections over time. Remote Access: we will develop new techniques supporting distributed access to digital col-lections in a heterogeneous networked environment. These techniques will be designed to satisfyaccess requirements across a spectrum that varies from very high quality local display and low-latency interactive manipulation, to remote access over wide-area, potentially low bitrate links. Display: we will develop new techniques for deploying scalable tiled projection displays forinstitutions and users who do not have access to sophisticated and dedicated technical support andhigh-cost hardware. These scalable display systems can be assembled from commodity hardwareand provide automatic, continuous calibration, and rapid reconfigurability.The motivation for this work stems from the need for high-quality preservation, access, and displaytechniques for digitized collections. Libraries, museums, and research scholars who want to acquire,manipulate, and provide remote access to (and high-definition display of)digitized artifacts need costeffective, non-intrusive, easily configurable methods for creating and viewing high-quality collections.New techniques will be evaluated on real-world library collections with particular focus on the preser-vation and dissemination of artifacts at our partner institution for this work, the Museo de Arte dePuerto Rico . With the aid of expert consultants who will contribute significant effort towards thisproject at our partner institution (see attached letter), we willdevelop and deploy a prototype systemfor acqusition and display using the techniques developed as part of this project. The resulting digitalarchive will be made accessible to patrons of the museum as well as a much larger audience around theworld via the Internet.We believe that this research will have significant immediate, medium-term and long-term impact.The immediate impact of the project will be the development of new acquisition, access, and displaymethods that will be deployed and tested at the Museo de Arte de Puerto Rico, making parts of theircollections available in forms not previously possible. In the medium term, our new technical approacheswill be valuable not only to the digital library community, but also to other research, instructional, andcommercial areas where configurable large-scale display systems are needed (e.g., classroom, researchvisualization centers, conference venues, etc). In the long term, we believe this proposed work hasthe potential to substantially impact the way people view and interact with data, whether the data isa collection of historical artifacts, a visual representation of a complex simulation, data/illustrationspresenting in the classroom, etc. Moreover, the cost effectiveness of our approach means that it will beaffordable to a wide range of users.
