An Annotation Tool for Video Understanding

摘要

The interest for developing annotation tools for interpretation of video sequences arises on the own necessity of conceptualizing scenes with a suitable degree of semantics for the application domain. In this paper we analyze the features that must be present in a video annotation tool for video understanding: the entities of interest that appear in each description level of the scene are analyzed and primary features (those that must be annotated initially) and derived features (those obtained automatically) are distinguished. Lastly, we present a video annotation tool based on the previous analysis, for which the design we have chosen is modular, reusable and user friendly.
