MPEG-7 question

["Jian Liang" <lj@cfar.umd.edu>]

Hi, everyone,

As a new comer, I have a question about MPEG-7 format.  I heard that there
are
more than a hundred standardized MPEG-7 Multimedia Description Schemes, but
I
couldn't find a single one.  Does anyone happen to know this issue?  Are
they
simply not public yet?  My purpose is to find some schemes to represent the
features, objects that found in a clip, and if there are standard schemes it
would be unnecessary to write my own.  Another thing is that the sample
MPEG-7
file shown on TREC 2002 Guidelines web site has the ability to represent the
existence and confidence of features, but is there a way to code, say, the
position of an object like a face?

Thanks,

-- Jian
