Study of Various Video Annotation Techniques

Abstract: Image annotation is an active field of research that serves as a precursor to video annotation. With the increase in the number of videos and important information present in them, there is need to annotate the videos. Annotation improves the efficiency of searching and retrieving the video. Video features are often inspired and sometimes directly borrowed from image techniques and many methods for image indexing are also easily applied to video. A human operator can specify annotations such as time, location and activity. More sophisticated annotations can be provided using automatic or semi-automatic techniques. There are various techniques that can be used for annotation; this paper discusses some of the techniques. Technique which employs the ontology, requires ontology language, web ontology language (OWL) is the ontology language that has gained importance. This paper also discusses ontology and knowledge base editor- Protégé.
