Blink and you'll miss it. This free program adds an extra level of security to your computer through your Webcam, associating your face with your username and password so you can start using your computer after a few seconds of looking at your Webcam.

When you install the program, it will offer to run a wizard to help you set it up. The wizard will autodetect your Webcam, and give you a choice if you have more than one. After giving you a screen to click through, which serves to give you more of a chance to compose yourself … Read more

The facial recognition technology that powers Face.com is now available to third-party developers. Those who are interested in using it inside of their applications will be able to take advantage of an open API that the company is making public Monday morning.

For consumers, Face.com's technology brings some very interesting things to the table. Face has already offered a tagging tool, as well as a recognition-based alert service for Facebook. But not everyone keeps their photos there. Using the new API, developers could build similar facial recognition tools into both desktop and Web based photo organizing apps … Read more

KeyLemon adds an extra layer of security to your computer log-in process by making your Webcam do all the heavy lifting. Instead of typing your password, KeyLemon 2.2 associates your face with your profile, and then regularly checks to make sure that the person sitting in front of the computer matches the image attached to that profile. If it doesn't think they match, the computer takes a photo via the Webcam and then automatically goes to hibernate.

The latest version of KeyLemon introduces a Firefox plug-in called LemonFox that lets users log in to three social-networking services using … Read more

KeyLemon logs you in to your computer by using your face. More than just a glorified Webcam tool, it regularly checks to make sure that it really is you using the computer. The latest version of the app also comes with a neat Firefox plug-in called LemonFox, for added protection when logging into Facebook, Twitter, and LinkedIn.

Once installed, the program's Wizard will walk you through creating a profile of your face, and link it to your computer's log-in. From there, KeyLemon defaults to checking the Webcam every 10 seconds, although you can always bypass it with your … Read more

Coca-Cola on Thursday launched a facial-matching Facebook application called the Coke Zero Facial Profiler.

As long as users have at least three photos of themselves in their Facebook profile, the application searches across other pictures from Facebook users that have used the app to find someone whose face matches theirs most accurately. Those that don't have three images can either upload a picture into the app from their desktop or capture a picture from their Webcam.

I had a chance to use the app this afternoon. After it is added to your profile, you can immediately direct it to … Read more

Computer scientists at Nanyang Technological University in Singapore are developing a system that could help autistic children identify the emotions of those around them by first locating the edges of faces, then finding crucial fiducial points to extract and process features, and finally classifying those features into corresponding emotions.

Their paper, "Towards a Portable Intelligent Facial Expression Recognizer," is available online through the journal Intelligent Decision Technologies (Volume 3:3).

"Emotion is a state of feeling involving thoughts, physiological changes, and an outward expression," write the paper's authors, Teik-Toe Teoh, Yok-Yen Nguwi and Siu-Yeung Cho … Read more

Last week's Picasa software update from Google brought with it a neat trick--facial recognition. But it wasn't the first free consumer photo-editing software to find faces. In January, Apple unveiled the latest version of iLife, which included an updated version of iPhoto that could detect and recognize faces in your photos. And this time last year, Microsoft released an updated version of its Windows Live Photo Gallery desktop software that could find faces inside of photos, though it couldn't (and still can't) recognize who's in them.

So, how do these three stack up? To figure that out, we put them to the test. Using 500 sample photos on fresh installs of each program, we tracked around how long each of the tools took to process all the photos, as well as some notable hits and misses from each.

To be fair, our results may not scale, or match the experience you will have. For one, we're using a test bed of photos that's almost entirely 12-megapixel JPEG files, whereas some people may be shooting smaller or larger files that may be in different formats and contain large groups of people--something that can slow these programs down. You're also likely to have a whole lot more than 500 photos sitting around on your computer; we certainly do.

Note: Adobe's PhotoShop Elements software (for Windows | Mac), which also includes a facial recognition feature was not included in this roundup since it's a paid application. Technically iPhoto is as well, but we included it since it comes free on all Macs.

iPhoto is the only product of the bunch that's Mac-only. It comes bundled with all new Macs, but the latest version (which includes face detection) must be purchased as a software upgrade if you've got iPhoto '08 or lower. We've included it in this roundup as a free product since it comes bundled with all new Macs.

Face scanning in iPhoto happens automatically, but it's largely a manual process, requiring users to "train" the system to recognize certain faces. The program took around nine minutes to scan through our 500 test photos and when it was done it didn't offer up any suggestions of photos with faces in them.

Instead, users are required to click on a photo with a face in it and hope the program picked it up. If it has, users can simply type the name in--which will auto complete if the person is in your Mac address book. If someone's face was not found, but you can see it in the photo, you can manually contain the face inside of a box, then tag it with their name.

After you add names to just few photos, iPhoto's system begins to piece together others that look the same--although it doesn't learn as fast as it does for photos where it already found the faces. In my testing, it only took two photos to get it to offer up some more suggestions. If those suggestions are correct, continuing to add them was just a matter of a few clicks.

iPhoto's system for doing this isn't perfect though.… Read more

Line up the freeware photo manager/editor combos and you'll quickly realize that Google's Picasa stands out in its class. The latest version, Picasa 3.5 (Windows | Mac), is no exception, offering one huge new feature and a few little ones, to offer you more choices for organizing and sharing photos from your desktop.

Facial recognition is the big news here, and Google's team has handily translated the face-tagging feature that it had implemented in the online version, Picasa Web Albums, to the desktop app. You can even download tags you used online into Picasa 3.5.… Read more

Roughly a year after rolling out facial recognition on its Picasa Web Albums site, Google on Tuesday is introducing an updated version of its Picasa software (for Windows | Mac) that can recognize faces in photos stored on users' computers.

Just as it does on the Web, Picasa scans your photos for faces, then groups together photos of specific people. It's then your job to tell it who they are as well as confirm its guesses. If someone you're tagging is in your Google address book, you can also look them up very quickly with auto-complete. Otherwise, Google gives you the option to add them as someone new; this information then gets synced back up your Google address book.

The system worked very well for me, but it was slow going. I had to leave the program running overnight for it to finish processing my 3,700 or so photos for faces. It also had my processor humming, since it was doing all the work on my machine instead of Google's giant server farm.

That's not to say Google hasn't included a few things to help speed up the process. For one, if you've got photos that are both hosted online and on your hard drive--and that have already been scanned for faces, the Picasa software can grab that information and add it to your local library. This saves it from having to scan the same photos twice.

And for photos it thinks contain people you've verified as contacts, it gives you quick "yes" and "no" buttons that can add or reject name tags. Oftentimes, clicking "yes" adds a few more suggestions for photos of that person that the program feels is safe enough to recommend. There's also a way to group accept or group decline its suggestions, which saves time you would have otherwise spent clicking the buttons one at a time.… Read more
