VideoLib: uma biblioteca digital de vídeo usando metadados Dublin Core e MPEG-7.

Abstract

Recently, a large amount of digital video can be found on the Web, and this number is increasing rapidly. The video manipulation becomes complex due to the great volume, semantic heterogeneity interpreted by different users and by the lack of adequate standards of indexing, resulting in a large effort of identification, search and management of the resources. Metadata must be associated to video in order to enable an efficient identification, indexing and semantic representation of it. Both Dublin Core and MPEG-7 standards provide a metadata set which enables the description of multimedia content. This paper presents a digital video library, known as VideoLib, which utilizes Dublin Core and MPEG-7 audiovisual descriptions to provide video content retrieval, with support to spatial and temporal dimensions.
