Lightroom: Please add face recognition to Lightroom (ability to specify region metadata)
Do you plan to implement a face recognition defined by keywords in Lightroom someday ?

-> I mean just detect faces with out saying who is there can help a lot.
Then add face recognition
But the most important thing is to be able to tag an image region (like a face for instance)
1. Start to make it general : ability to associate a region (saved in xmp) with a Keyword (normal kind of keyword we have already)
2. then these Keywords can be used for face taging
3. then in the database some of these keywords can be associated to face characteristic allowing an algorithm to make face recognition.
Finally the most important in face recognition is not how well the algorithm performs, but how well results are presented so that you can easily correct any errors or validate good guess.
Maybe we can group faces by similarities (with a given threshold) like Picasa seem to do.
A same person may then appear in different such group (because the person got older, or ...) and a same keyword (person keyword for instance) would then be associated with 2 or more face characteristic. this way we can eleminate the problems of photoshop element who get worse at guessing people faces when you have tagged too many faces of the same person (old faces pollute the ability to detect youger faces and vice versa)

LR integration with Keywords is crucial, and possibly a way to integrate EXISTING Keywords to help with the detection would be great.
I typically take have a shooting spree where I have taken dozens of photos with the same people, so presenting that / building an algorithm should prefer that I would hope.

See "Guidelines for Handling Image Metadata, Version 2", section 5.9 for more details.

I would hope though that if Adobe do add this feature (please do) that they do not get tempted to incorporate this into social networking sites... I do not like the idea that people can tag your picture on line without your permission. let alone be able to publish your photo online.....

So Apple has it, and it looks like Google will be using it. It sure would be easier to keyword photos with face recognition, assuming it worked well. Instead of viewing it as a gimmick for the masses, as opposed to serious photographers, try viewing it as a workflow automation improvement that will become a requirement over time.
Fast forward a few years. Imagine LR creates an XML file, or mini DB of attributes attached to each photo, derived from things like image processing, GPS coordinates and date/time. Potential keywords could be presented for easy selection like: Dad, Julie, John Warnock, Christmas, Wedding, River, Mountains, Horse, Fog, Dawn, Yosemite, Motorcycle, Woman, Rain, Tornado, Fire, Red, Fruit ... You get the idea.
This kind of stuff will be prevalent for still and video captures in a few years, by all the computer-based applications (desktop and laptop and maybe tablet).
So Adobe - lead or follow?

I gave it a folder of about a thousand images, pretty much all of them of people (my kids, mostly). It took about 10 minutes, and came up with a bunch of faces for me to identify. That took a few minutes. Done right?
I then went through image-by-image and had a look. It missed about 75% of the people in the images, not identifying them as faces at all. This seemed to be caused by the fact that the full face wasn't in the image, either in profile, partially obstructed, wearing sun glasses, or something else.
I then proceeded to manually do what it hadn't done. It took a little over two hours.
Since I had to touch each image manually anyway, I estimate that the face recognition technology only saved me a few minutes over doing the whole thing myself manually.
I think this is a difficult problem and I don't see a way to overcome it.

more and more camera have this feature, to adjust focus on the faces, even dslr (in live view mode). some of them store this info in metadata. So if lightroom could read that, this could help save computing time?

This seems to me to be an ideal function to be addressed by a third party addin.
