INTRODUCTION

The volume of video data is growing exponentially. This data need to be annotated to facilitate search and retrieval, so that we can quickly find a video whenever needed.

Manual Annotation, especially for such volume, is time consuming and would be expensive. Hence, automated annotation systems are required.

 

AIM

Automated Semantic Annotation of wide-domain videos (i.e. no domain restrictions). This is an important step towards bridging the “Semantic Gap” in video understanding.

 

METHOD

1. Extracting “Video Signature” for each  video.
2. Match signatures to find most similar  videos, with annotations
3. Analyse and process obtained annotations, in consultation with Common-sense knowledge-bases
4. Produce the suggested annotation.

EVALUATION

• Two standard, and challenging  Datasets  were used. TRECVID BBC Rush and UCF.
• Black-box and White-box testing carried out.
•Measures include: Precision, Confusion Matrix.

CONCLUSION

•Developed an Automatic Semantic Video Annotation framework.
•Not restricted to a specific domain videos.
•Utilising Common-sense Knowledge enhances scene understanding and improve semantic annotation.

Conference Paper Accepted – DHS virtual training

Amr Ahmed DCAPI blog, Uncategorized, Virtual Reality , , , , ,

Another conference paper been accpeted, and will be published in June 2012. This paper reports on the development of the 2 3D tracking prototypes for virtual reality training of surgeons (in vitro / Off patient), especially for the Dynamic Hip Screw surgical procedure (in particular; the insertion of the guide-wire). The aim is to develop the cognitive coordination, in particular the Brain/Hands/Eyes coordination that is crucial for such procedure. But through an affordable system that uses Commercial off-the-shelf (COTs)  components.

This work is in collaboration with Prof. Maqsood, Consultant Trauma and Orthopaedic surgeon in the Lincoln Hospital.

Over 40 researchers, from vision and language areas, attended and it was a good opportunity for networking and exchange of contacts and ideas. Posters and sides will be available on the network’s website in the near future
