New Conference paper Accepted to the “ World Congress on Engineering”: Video Matching Using DC-image and Local Features

New Conference  paper Accepted to the “ World Congress on Engineering”

New Conference paper accepted for publishing in  “World Congress on Engineering 2013“.

The paper title is “Video Matching Using DC-image and Local Features ”

Abstract:

This paper presents a suggested framework for video matching based on local features extracted from the DC-image of MPEG compressed videos, without decompression. The relevant arguments and supporting evidences are discussed for developing video similarity techniques that works directly on compressed videos, without decompression, and especially utilising small size images. Two experiments are carried to support the above. The first is comparing between the DC-image and I-frame, in terms of matching performance and the corresponding computation complexity. The second experiment compares between using local features and global features in video matching, especially in the compressed domain and with the small size images. The results confirmed that the use of DC-image, despite its highly reduced size, is promising as it produces at least similar (if not better) matching precision, compared to the full I-frame. Also, using SIFT, as a local feature, outperforms precision of most of the standard global features. On the other hand, its computation complexity is relatively higher, but it is still within the real-time margin. There are also various optimisations that can be done to improve this computation complexity.

Well done and congratulations to Saddam Bekhet .

OpenCV workshop

Saddam Bekhet, member of the DCAPI group  demonstrated  workshop about Using OpenCV  with Visual Studio 2010 Express edition on 23/01/2013 . In addition a demonstration about basic OpenCV operations (loading & manipulating images) and advanced operations (face detector & tracker from live camera stream) was demonstrated.

Summary of installation settings of OpenCV :
1- Download OpenCV files  http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.0/
2- Download CMAKE http://cmake.org/cmake/resources/software.html
3- Use CMAKE to generate OpenCV library AND DLL’s  and use x64 architecture or the architecture what ever suites you  in VS2010
4-Open OpenCV build folder and search for “OpenCV.sln”  then compile it.
5- Remember to but openCV DLL’s beside The Debug \EXEDirectory of your project in Visual Studio
6- Rememeber to install intel threading block http://threadingbuildingblocks.org/ and put the DLL called  tbb.dll in  your visual studio debug\EXE

Include direcories in VS2010 Project–>Properities–>VC++ Directories

Make sure to reblace “X” in the previous file names with correct naming of the generated OpenCV library files for example on my machine it is “opencv_nonfree242d.lib”

Two Presentations and Posters in the Vision & Language Network workshop

Three members of the Lincoln School of Computer Science, and the DCAPI group, have attended the Vision & Language (V&L) Network workshop, 13-14th Dec. 2012 in Sheffield, UK.

Amr Ahmed, Amjad Al-tadmri and Deema AbdalHafeth attended the event, where Amjad and Deema delivered  2 oral presentations and 2 posters about their research work:

1. VisualNet: Semantic Commonsense Knowledgebase for Visual Applications
2. Investigating text analysis of user-generated contents for health related applications

Abstracts are available on ( http://www.vlnet.org.uk/VLW12/VLW-2012-Accepted-Abstracts.html)

Congratulations for all involved.

The event included tutorial sessions (Vision for language people, and language for vision people). We had an increased presence this year.

Last year, we had a good presence in the last year’s workshop (http://amrahmed.blogs.lincoln.ac.uk/2011/09/19/vl-network-workshop-brighton/), had good discussions and useful feedback on the presented work.

Looking forward for similar, if not even better, experience this year.

Best wishes for the presentations.

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
