In this paper, we describe description schemes (DSs) for image, video, multimedia, home media, and archive content proposed to the MPEG-7 standard. MPEG-7 aims to create a multimedia content description standard in order to facilitate various multimedia searching and filtering applications. During the design process, special care was taken to provide simple but powerful structures that represent generic multimedia data. We use the eXtensible Markup Language (XML) to illustrate and exemplify the proposed DSs because of its interoperability and flexibility advantages. The main components of the image, video, and multimedia description schemes are object, feature classification, object hierarchy, entity-relation graph, code downloading, multi-abstraction levels, and modality transcoding. The home media description instantiates the former DSs proposing the 6-W semantic features for objects, and 1-P physical and 6-W semantic object hierarchies. The archive description scheme aims to describe collections of multimedia documents, whereas the former DSs only aim at individual multimedia documents. In the archive description scheme, the content of an archive is represented using multiple hierarchies of clusters, which may be related by entity-relation graphs. The hierarchy is a specific case of entity-relation graph using a containment relation. We explicitly include the hierarchy structure in our DSs because it is a natural way of defining composite objects, a more efficient structure for retrieval, and the representation structure used in MPEG-4. We demonstrate the feasibility and the efficiency of our description schemes by presenting applications that already use the proposed structures or will greatly benefit from their use. These applications are the Visual Apprentice, the AMOS-Search system, a multimedia broadcast news browser, a storytelling system, and an image meta search engine, MetaSEEk.

For such an implied change in phase-space topology the particle is almost always forced to cross singular surfaces during one mirror transit and thereby scatter appreciably in a number of transit times. Figure 4 illustrates this well as the field configuration and initial particle phases are identical to those of Fig. 3, except that in Fig. 4 the potential

This paper describes a face image database which has been created and developed at Kodak as a common database for direct benchmarking of automatic face detection and recognition algorithms. This consumer applicationoriented face image database is composed of two main sub-databases, one for face detection, and one for face recognition. The database is intended to be distributed to researchers both inside and outside of Kodak working in face detection and recognition research. The database contains pictures taken using consumer digital cameras, scanned in from a photo scanner, as well as pictures from Kodak Image Magic picture disks. The details of the face database such as the development process and the image file formats, are described, together with brief discussion on some application scenarios, as well as current benchmarking activities.
