Multimedia content acquisition and processing in the MIRACLE system
Zhu Liu, David C. Gibbon, Behzad Shahraray · 2006
This paper describes the content acquisition, indexing and repurposing components of the MIRACLE system. MIRACLE is an ongoing research project at AT&T Labs aimed at creating automated content-based media processing algorithms and systems to collect, organize, index, and repurpose video and multimedia information. While the retrieval engine and the user interface are the most visible part of the query process, performing the required processing to extract the relevant information and generate the indices for the retrieval engine is the most crucial and challenging component of the overall system. Moreover, the utility of the system is highly dependent on the quality and quantity of the acquired data. We describe an acquisition system that takes advantage of Personal Video Recorder (PVR) functionality of Windows OS to acquire high-quality video and the associated metadata. We discuss several processing algorithms for extracting information that enable efficient searching and browsing of more than 32,000 video programs. 1.
