RE: Ookles

Raphaël, All,
 
Happy New Year to all of you as well. Thanks for this pointer--looks great;
I'm _very_ eager to see it working :) though I wonder what they use to do the 
face/object recognition and the so called "intelligent automatic tagging" ...
 
In this context I was contemplating about (automated) description of
real-world media; imagine not only still images, but video clips being 
"tagged intelligent"--what could the requirements for the KR-part look like?
The following example might give you an idea what causes me some headache:
 
Take a video clip with a duration of one hour that is described with MPEG-7. 
Several visual features (F) as colour, shape, texture, etc. are extracted for
a number of spatial segments (S) per key frame (K). Further, a kind of multimedia 
ontology (e.g. [1]) is then used to represent the MPEG-7 descriptors formally 
(viz. on a RDF/OWL basis); an average number of RDF triples is assumed for each
descriptor (TD). 
 
An estimation of the resulting RDF graph size then is F*K*S*TD.
Let us assume that we want to capture 10 features, some 1000 key frames
may exist, 10 spatial segments are marked up, and finally 10 triples are
required per descriptor. This yields a total RDF graph size of _1 million triples_,
just for describing some low-level features of an hour of video footage.
 
What do you think?
 
Cheers,
       Michael

Dear MMSemers,

First of all, let me wish to all of you an Happy New Year 2007 !

Something interesting for the Multimedia Semantics XG, the Ookles
platform should be launched in 2007, see: http://www.ookles.com/
Ookles can be defined by the following equation: Ookles =
Flickr+Riya+YouTube
An interesting technical review can be read at:
http://www.techcrunch.com/2006/12/18/ookles-to-launch-in-early-2007/

Among others, Ookles propose to organize automatically your photos and
has developped the following features:
    * Facial and object recognition finds the people you care about
    * Automatic organization of your photos
    * Intelligent automatic tagging for your media
    * Controls for security and viewer safety
    * Import and export from all popular photo and video sharing
websites
    * All in an easy web service accessible anywhere

Best regards.

    Raphaël
