Abstract [en]

The Motion Picture Experts Group (MPEG) has initiated a new work item known as MPEG-7, Multimedia Content Description Interface. This work item will provide a standard set of Descriptions Schemes and Descriptors as well as a language to specify them, called Description Definition Language (DDL). These Descriptors will provide a way to extend the capabilities of proprietary solutions in identifying multimedia content on the Web, to allow fast and efficient searching and retrieving of material according to the user's interests. This material will include: still pictures, graphics, 3D models, audio, speech, video, and information about how these elements are combined in a multimedia presentation (scenarios, composition information). In this thesis we will look at one of the applications of MPEG-7, Universal Multimedia Access (UMA)[8], which aims at providing a common way to access multimedia files on the Web, while adapting them to the client being used. In particular, we focus on one aspect of UMA, video summarization, which is closely related to the Key Frames and Fidelity descriptors of the Visual part of the eXperimentation Model (XM). We will describe a new algorithm to perform video summarization, based on feature points.
