CAREER: Fast Access Techniques for Video Information Retrieval

数字音频和视频作为在计算机和通信系统中操纵的数据越来越普遍。信息检索机制的使用（例如，Mosaic、Gopher）正在迅速成为网络带宽和存储的主要消费者。在没有过滤机制或分层编码方案的情况下，必须处理大量数据以产生所寻求的信息。为了支持诸如娱乐、远程学习、家庭保健和远程办公的未来交互式信息递送服务，需要提供用于定位、访问和递送大量视频内容的有效手段。本提案中描述的研究旨在实现在浏览和检索此视频内容期间的快速访问。 "快速获取“建议通过以下办法的结合来实现：（1）开发用于视频内容的域特定信息模型，（2）开发用于音频/视频域中的分级编码和可缩放递送的自动信息捕获，（3）使用针对信息模型定制的视频查询/接口技术，以及（4）将信息内容映射到所开发的递送协议。预期的结果是技术和概念证明所提出的快速访问。 建议的教学活动包括课程的开发，以反映计算机工程师不断变化的需求，以及基于计算机的教学工具的使用，评估和推广。

Digital audio and video are increasingly common as data that are manipulated in computer and communication systems. The use of information retrieval mechanisms (e.g., Mosaic, Gopher) that allow the exchange and display of audio, stills, and video is rapidly becoming a major consumer of network bandwidth and storage. Without filtering mechanisms or hierarchical coding schemes one must process a great deal of data to yield sought information. To support future interactive information delivery services such as entertainment, distance learning, home health care, and telecommuting, there is a need to provide efficient means for locating, accessing, and delivering enormous amounts of video content. The research described in this proposal seeks to enable fast access during browsing and retrieval of this video content. The ``fast access'' is proposed to be achieved by a combination of approaches involving: (1) development of domain-specific information models for video content, (2) development of automated information capture for hierarchical coding and scalable delivery in the audio/video domains, (3) use of video query/interface techniques tailored to the information models, and (4) mapping of information content to developed delivery protocols. Anticipated results are techniques and proof of concept for the proposed fast access. Proposed teaching activities encompass the development of courses to reflect the changing needs of computer engineers and the use, evaluation, and promotion of computer-based instructional tools.
