Special Session on object-based video: extraction tools, evaluation metrics and applications



Motivation: The representation of video information in terms of its content is at the foundation of many multimedia applications, such as broadcasting, content-based information retrieval, interactive video, remote surveillance and entertainment. In particular, object-based representation consists in decomposing the video content into a collection of meaningful objects. This approach offers a broad range of capabilities in terms of access, manipulation and interaction with the visual content. The basic difference when compared with pixel-based procedures is that instead of processing individual pixels, image objects are used in the representation.
To exploit the benefits of object-based representation, multimedia applications need automatic techniques for extracting such objects from video data, a problem that still remains largely unsolved.


Aim of the special session: The goal of this special session is to bring together researchers who are working on different aspects of object-based video analysis and processing, ranging from object extraction to object-based applications. Areas of interest of the special session include (but are not limited to):

  • Video object segmentation
  • Video object tracking
  • Automatic and semiautomatic video object extraction
  • Semantic aspects in video object extraction
  • Performance evaluation metrics
  • Examples of object-based systems for Video Editing, Visual Surveillance, Augmented Reality, Video Coding, Universal Multimedia Access, Video Databases, Ambient Intelligence
