We present a Web-based video annotation system named iVAS (intelligent Video Annotation Server) that allows users to associate Internet video content with annotations. The system analyzes video content to acquire cut/shot information and color histograms. Then it automatically generates a Web document that allows the users to edit the annotations. We also present two application systems based o...

The tremendous growth in video data calls for efficient and flexible access mechanisms. In this paper, we propose an ontology-driven framework for presentation video annotation and access. The goal is to integrate ontology into video systems to improve users’ video access experience. To realize ontology-driven video annotation, the first and foremost step is video segmentation. Current research...

Surveillance video is characterized by short periods of activity in a small region of the image, and long periods of inactivity. When transmitting such video sequences over a wireless network, it is important to dynamically adapt the encoding of each stream according to both the video content and the underlying network conditions. We propose a video surveillance system that exploits H.264/AVC c...

Video modeling and annotating are indispensable operations necessary for creating and populating a video database. To annotate video data effectively and accurately, a video content description ontology is first proposed in this paper, we then introduce a semi-automatic annotation strategy which utilize various video processing techniques to help the annotator explore video context or scenarios...

This paper presents techniques for multimedia annotation and their application to video summarization and translation. Our tool for annotation allows users to easily create annotation including voice transcripts, video scene descriptions, and visual/auditory object descriptions. The module for voice transcription is capable of multilingual spoken language identification and recognition. A video...

Semantic annotation of multimedia data for improving search engine performance is an important issue. We have focused on the automated annotation of video recordings of university lectures. Most times these lectures are supported by a desktop presentation provided by the lecturer. This presentation in general contains an outline of the given lecture and thus, enables automated annotation of the...
