Abstract
MPEG-7 is an extensive multimedia metadata standard covering a huge number of aspects of metadata. However, as with most metadata standards details of usage and application of the standards are – at least partially – open to interpretation. In case of MPEG-7storage and transmission of high level metadata on concept level are defined but retrieval methods are not proposed. So if for instance a user annotates photos using the MPEG-7 semantic description scheme, there are no standardized ways to retrieve the photos based on the annotation. In this paper we propose metrics for retrieval based on the MPEG-7 semantic description scheme and evaluate them in a digital photo retrieval scenario.
