Giró-i-Nieto X, Camps N, Marqués F. Region-based annotation tool using partition trees. In International Conference on Semantic and Digital Media Technologies. Genova, Italy; 2007. pp. 3–4.


This paper presents an annotation tool for the man- ual 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.
