The MPEG-7 Standard, due for release this spring, has a strong information retrieval focus, including face recognition technology fast enough to locate a scene containing a particular person out of 24 hours of video in one second on a conventional computer.
There are, of course, non-evil uses of face-recognition. Say you had thousands of hours of Congressional committee hearings on videotape. There is decent voice-to-text technology out there that will produce reasonably good transcripts. But for indexing purposes, you really need to know who was speaking. Now you can do all your indexing automatically.
this is, for now, a hypothetical case, but it's something that has been discussed in my presence

very cool. but what happened to mp5 and mp6? And when are we going to see applications that use mp7?

Stop the presses. Now I'm confused. The same web site has an article about the September 2001 release of MPEG-7. So, I think the Spring 2004 release must refer to the Version 2 developments discussed in Section 5.

The idea sounds cool but those links are pretty boring.

MPEG is (or is supposed to be) a standard. Somehow I find it hard to believe these (very hard) problems that haven't been solved yet are suddenly going to get solved and rolled into a nice standard package any time soon.

as in a friend of a friend that developed a system for his catflap, recognising whether the cat was carrying a mouse in its mouth, and whether it would let the cat in as result. not necessarily catface-recognition, ill admit, but still pretty fucking clever.

* Play a few notes on a keyboard and retrieve a list of musical pieces similar to the required tune, or images matching the notes in a certain way, e.g. in terms of emotions.
...
* On a given set of multimedia objects, describe movements and relations between objects and so search for animations fulfilling the described temporal and spatial relations.
* Describe actions and get a list of scenarios containing such actions.
No way. What the fuck does that meta-data look like? Who made it? How is it structured I don't think any technology present or future will ever be able to peruse a video and find all of the 'sad' passages (what woud this even mean? Are your sad passages the same as mine?).

Yes, but how can it be used for pr0n?
finally someone starts asking the important questions...

In related news, Kazaa Lite 2005 claims to include a new "Find more with this clitoris" function.

Is that real? If so, it's pretty amazing.

Someone is claiming once again that they've got face recognition nailed down? In one second on an "average computer", no less? And it requires only 253 bits to accurately identify a face?
That's simply awesome. Surely they'll make tons of cash. Just as long as they do not mention their heavy crack-smoking habit when pitching it to law enforcement.
Once again.
/Mpeg4 (AKA DivX) is pretty damn slick, BTW

A few query examples are:
* Play a few notes on a keyboard and retrieve a list of musical pieces similar to the required tune, or images matching the notes in a certain way, e.g. in terms of emotions.
* Draw a few lines on a screen and find a set of images containing similar graphics, logos, ideograms,...
* Define objects, including color patches or textures and retrieve examples among which you select the interesting objects to compose your design.
* On a given set of multimedia objects, describe movements and relations between objects and so search for animations fulfilling the described temporal and spatial relations.
* Describe actions and get a list of scenarios containing such actions.
* Using an excerpt of Pavarotti’s voice, obtaining a list of Pavarotti’s records, video clips where Pavarotti is singing and photographic material portraying Pavarotti.
