This paper describes a technical solution for automated slideshow generation by extracting a set of high-level features from music, such as beat grid, mood and genre and intelligently combining this set with image high-level features, such as mood, daytime- and scene classification. An advantage of this high-level concept is to enable the user to incorporate his preferences regarding the semantic...
During the last years, a number of search and retrieval methods for audio and visual content were described in literature. Also cross-modal approaches started to emerge recently. All search methods are based on audiovisual fingerprints, which are extracted from the audiovisual data prior to the actual search. Since the most data are available in the compressed domain, they must be decompressed prior...
One of the latest developments of the MPEG committee is the Query Format for search and retrieval of multimedia content. This language constitutes the interface between a client and a search engine for searching multimedia data. Another possible scenario is the use of a service provider, which accepts and understands a query from a client and forwards parts of the query to one or more specific databases...
Within the last years the amount of digital media has been spread due to efficient media encoding algorithms. Hence, a large number of audio and video files are stored on the users hard disks and on popular video community platforms. Due to the lack of suitable or disobeyed metadata standards, the description of these data is often missing or misleading. Therefore, audio and visual identification...
Personal information consumption became more and more important due to the huge number of existing information channels and the broad range of available information. While obtaining information from the Internet, it is usual to create individual profiles in order to consume personalized content based on the users preferences, e.g. within news portals. The traditional broadcast domain does not offer...
We describe an efficient conversion method, which directly converts a desired spectral representation from compressed audio material. The conversion method provides a feature extraction algorithm with a suitable complex frequency representation of an audio signal. The presented conversion allows us to trade off computational complexity with accuracy. We then test several operating points with an MPEG...
The growth of multimedia is increasing the need for standards for accessing and searching distributed repositories. The moving picture experts group (MPEG) is developing the MPEG query format (MPQF) to standardize this interface as part of MPEG-7. The objective is to make multimedia access and search easier and interoperable across search engines and repositories. This article describes the MPQF and...
Due to the growing number of digital audiovisual media during the last years, the amount of metadata to describe the content increased significantly. In order to improve the search and retrieve of such data, the metadata standard MPEG-7 has been established. This international standard facilitates many application domains and is probably the richest multimedia metadata set available today. However,...
In recent years, the amount of Internet accessible digital audiovisual media files has vastly increased. Therefore the need to describe the media (by way of metadata) has also increased significantly. MPEG-7 (finalized in 2001) provides a comprehensive and rich metadata standard for the description of multimedia content. Unfortunately, a standardized query format does not exist for MPEG-7, or other...
