"Rapid 3D scene modelling from video clips"

William Clocksin, Oxford Brookes University UK



Friday 30th November 2007, 2-3pm GMT Room 1.10, Kilburn Building The University 
of Manchester

I will describe the VideoTrace system developed in a collaboration between 
Oxford Brookes University and the University of Adelaide. VideoTrace 
interactively generates realistic 3D models of objects from video-models that 
might be inserted into a video game, a simulation environment, or another video 
sequence.



The user interacts with VideoTrace by tracing the shape of the object to be 
modelled over one or more frames of the video. By interpreting the sketch drawn 
by the user in light of 3D information obtained from computer vision 
techniques, a small number of simple 2D interactions can be used to generate a 
realistic 3D model.



Each of the sketching operations in VideoTrace provides an intuitive and 
powerful means of modelling shape from video, and executes quickly enough to be 
used interactively. Immediate feedback allows the user to model rapidly those 
parts of the scene which are of interest and to the level of detail required. 
The combination of automated and manual reconstruction allows VideoTrace to 
model parts of the scene not visible, and to succeed in cases where purely 
automated approaches would fail.

Anyone wishing to view a seminar via Access Grid should note the following. 
Please check the Jabber room shortly before the start of the seminar to find 
out whether IGPix or ScreenStreamer is to be used.



Jabber room: 
university-of-manchester-(1.10)(sam.ag.manchester.ac.uk)@conference.mcs.anl.gov



ScreenStreamer:

    * Preferably use ScreenStreamer software - go to 
http://www.memetic-vre.net/software/ScreenStreamer/ScreenStreamer.php, and 
select room "University of Manchester (1.10)" from the AGSC section. Grab the 
screen feed (by clicking on it) from the screenstreamer window and resize it - 
more info can be found on http://www.memetic-vre.net/software/ScreenStreamer.

    * Alternatively, the screenshot (not animated) can be accessed at 
http://192.150.184.66:7890 (this IP might change for some sessions - please 
check Jabber).



For technical assistance regarding the Access Grid, please contact the Access 
Grid Support Centre. Non-UK Access Grid nodes are advised to contact the Access 
Grid Support Centre to check connectivity before the date of the seminar.



If possible, please let us know in advance if your site intends to join a 
seminar.
