A fully automated content-based video search engine supporting spatiotemporal queries

The rapidity with which digital information, particularly video, is being generated has necessitated the development of tools for efficient search of these media. Content-based visual queries have been primarily focused on still image retrieval. In this paper, we propose a novel, interactive system on the Web, based on the visual paradigm, with spatiotemporal attributes playing a key role in video retrieval. We have developed innovative algorithms for automated video object segmentation and tracking, and use real-time video editing techniques while responding to user queries. The resulting system, called VideoQ , is the first on-line video search engine supporting automatic object-based indexing and spatiotemporal queries. The system performs well, with the user being able to retrieve complex video clips such as those of skiers and baseball players with ease.

Searching and editing MPEG-compressed video in a distributed online environment

Image technologies provide critical components for achieving various Web-based multimedia applications. We identify key technical challenges in todays image/video applications on the WWW. We present two prototype systems, a video search engine (WebSEEk) and a compressed video editor (WebClip), to demonstrate technical challenges and viable solutions. We also discuss major issues in developing next-generation, scalable solutions for large-scale, distributed on-line environments.

WebClip: a WWW video editing/browsing system

Abstract. WebClip (on-line demo at http://www.ctr.columbia.edu/webclip) is a compressed video searching and editing system operating over the World Wide Web. WebClip uses a distributed client-server model including a server engine for content analysis/editing, and clients for interactive controls of video browsing/editing. It specializes several unique features, including compressed-domain video feature extraction and manipulation, multi-resolution video access, content based video browsing/retrieval, and a distributed network architecture.

A distributed system for editing and browsing compressed video over the network

WebClip is a complete working prototype for editing/browsing MPEG-1 and MPEG-2 compressed video distributively over the World Wide Web. It uses a general system architecture to store, retrieve, and edit MPEG-1 or MPEG-2 compressed video over the network. It uses an innovative distributed network support architecture. It also uses our unique CVEPS (Compressed video editing, parsing, and search) technologies.

Methods and architecture for indexing and editing compressed video over the world wide web

We present a new framework for distributed video editing and browsing over the network. This framework uses a distributed client-server model including a server engine for content analysis/editing, and clients for interactive controls of video browsing/editing. It utilizes several unique features, including compressed-domain video manipulation, multi-resolution video access, content based video browsing/retrieval, and a distributed network architecture. We have developed a complete functional prototype, CVEPS, which includes a compressed domain video analysis and editing engine, and a JAVA based user interface. It has been incorporated into a World Wide Web application, WebClip, for editing compressed video over the Web.
