Region-based annotation tool using partition trees

This paper presents an annotation tool for the manual and region-based annotation of still images. The selection of regions is achieved by navigating through a Partition Tree, a data structure that offers a multiscale representation of the image. The user interface provides a framework for the annotation of both atomic and composite semantic classes and generates an MPEG-7 XML compliant file.Postprint (published version

System architecture for indexing regions in keyframes

This paper describes the design of an indexing system for a video database. The system uses region-based manual an- notations of keyframes to create models to automatically annotate new keyframes also at the region level. The pre- sented architecture includes user interfaces for training and querying the system, internal databases to manage ingested content and modelled semantic classes, as well as communi- cation interfaces to allow the system interconnection. The scheme is designed to work as a plug-in to an external Mul- timedia Asset Management (MAM) system.Postprint (published version
