VideoLib: a video digital library with support to spatial and temporal dimensions

ABSTRACT

Nowadays, a large amount of digital video can be found on the Web, and this number is increasing rapidly. Metadata should be associated to video in order to enable an efficient identification, indexing and semantic representation of it, so that effective video information retrieval tools can be built. Both Dublin Core and MPEG-7 standards provide a metadata set which enables the description of multimedia content. This paper presents a video digital library, known as VideoLib, which utilizes Dublin Core and MPEG-7 audiovisual descriptions to provide video content retrieval. Mainly, VideoLib enhances video retrieval by introducing spatial and temporal operators.
