WIAMIS 2008 talk: Video summarization through acceleration

With the contribution “Redundancy Removing by Adaptive Acceleration and Event Clustering for Video Summarization” Bernard Mérialdo presented a very interesting approach to video summarization. Beside other methods the video is accelerated. Based on the overall motion the actual amount of acceleration is adapted. Furthermore they apply hierarchical clustering on fixed size segments to select most important parts. Therefore the video is faster when not very much motion is going on and slower if fast motion is characteristics for a video segment. Nice added value was hat he described the RUSHES track of TRECVID and the evaluation process. Experts evaluate the accuracy of the summaries and weight them with extraction time and size of the summary.

Some thoughts on the WIAMIS keynote of H. Bischof

In the morning I was listenting to the talk of Horst Bischof on robust people detection in surveillance scenarios. In my opinion he gave a great talk: He manages to show the nature and results of their research and motivate the usefulness and significance of results based on context and related work. He points out what the achievements are and what hasn’t been touched by his research group and why. He also visualized his results using videos which was appreciated by the audience. If I findout where the videos can be found I’ll blog the link.

WIAMIS 2008 starts today …

The 9th International Workshop on Image Analysis for Multimedia Interactive Services (WIAMIS) takes place for the next three days in Klagenfurt, Austria. As we (the Multimedia Metadata Community) organized a special session there we will gather on Thursday latest and discuss current and upcoming research topics.

While I still have some things to prepare for tomorrow I will visit Horst Bischof’s keynote talk on “Robust Person Detection for Surveillance using Online Learning” and I hope I will find some time to blog about the conference.

Deadline Extension: I-Media Special Session on Multimedia Metadata

The paper submission deadline has been extended to April 28, 2008.

Original CfP: 

Studies show that sales of digital capture devices like video camera, digital photo cameras, or mobile phones with digital cameras are still rising. Therefore it can be expected that the number of created digital multimedia content will rise dramatically in future. Multimedia metadata is currently the only way to cope with problems like semantics based retrieval or organization of content and provides means to specify adaptation and delivery constraints and rules. Within this special session the importance of metadata for media technologies is discussed. We encourage the submission of high quality scientific work as well as application papers. Topics include but are not limited to:

  • Multimedia technologies and metadata in the social web
  • Multimedia semantics
  • Annotation of multimedia content
  • Metadata in pervasive multimedia computing
  • Metadata for new media
  • Studies and surveys in context of multimedia metadata and new media

We encourage the submission of high quality scientific work as well as application papers.
