The VideoAnnEx annotation tool assists authors in the task of annotating video sequences with MPEG-7 metadata. Each shot in the video sequence can be annotated with static scene descriptions, key object descriptions, event descriptions, and other lexicon sets. The annotated descriptions are associated with each video shot and are stored as MPEG-7 descriptions in an output XML file. VideoAnnEx can also open MPEG-7 files in order to display the annotations for the corresponding video sequence. The annotation tool also allows customized lexicons to be created, saved, downloaded, and updated.
