Population and Query Interface for a Content-Based Video Database

Abstract

Abstract. In this paper we describe the first full implementation of a contentbased indexing and retrieval system for MPEG-2 and MPEG-4 videos. We consider a video as a collection of spatiotemporal segments called video objects; each video object is a sequence of video object planes. A set of representative video object planes is used to index each video object. During the database population, the operator, using a semi-automatic outlining tool we developed, manually selects video objects and insert some semantical information. Lowlevel visual features like color, texture, motion and geometry are automatically computed. The system has been implemented on a commercial relational DBMS and is based on the client server paradigm. The database population client is a stand-alone Windows application; the querying of the system is performed with a web-based client. To test the system we indexed a number of videos taken from Italian soccer championship games. A few examples of queries in this particular domain are reported and results appear very promising.

“…Ardizzone et al [7] use the MPEG-4 coding to extract some VO (Video Object) and VOP (Video Object Plane), corresponding to the trajectories. MPEG-7 [8] provides a rich set of standardized tools to describe video content.…”
