Log in with your face

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

Facial recognition face-off: Three tools compared

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.

The apps and workflows

iPhoto

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

Picasa 3.5 finds friends' faces in photos (video)

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

Picasa 3.5 brings facial recognition to the desktop

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

Soon, billboards that know male from female

Singapore's Agency for Science, Technology, and Research (A*Star) has developed a gender recognition system that could change the way advertising works in the future.

The technology uses sophisticated algorithms to differentiate facial features of males and females. However, unlike Face Detection 3.0, which is employed in point-and-shoots such as the Fujifilm FinePix F200EXR, the gender recognition system can only detect faces that are facing the camera.

The A*Star-developed system is bring displayed at CommunicAsia 2009 held at the Singapore Expo. A representative at the agency's booth told us the technology is focused on advertising, so … Read more

Viewdle makes those horrid in-text links useful with celebrity mugs

You know my stance on bad e-cards, and in the same vein comes my dislike for in-text ad links that you find on some blogs. I'm not talking about Snap's little Web site previews with its Snap Shots service, which people either love or hate, but the IntelliTXT stuff--the kind where you accidently moved your mouse near one and it opens up an ad that doesn't go away for several seconds. Ryan Block from Engadget had a good missive on the matter back in August of last year, and I have to agree with the guy that it ruins the reader experience.

With that said, I'm really digging Viewdle's new Name Widget service, which will cross check any names you mention in a blog post and serve up a tiny little video morsel of the person's face when you hold your cursor over his or her name. The video clips in question come from larger pieces of video that have been run through a facial recognition database and cropped down to fit in an area the size of your thumb. Anyone can add to their blog posts or Web site free of charge with a few lines of JavaScript.

The best part is, to actually trigger the video you need to hold your mouse over the link for a good 3 seconds before the video starts playing, so your reading experience won't be too bothered if you make the occasional brush. If you end up actually clicking the name link, Viewdle will kick you over to Reuters, which has a bunch of links to videos where the person appears. Each link jumps you right to that spot. However, Viewdle doesn't require you to link back to its Reuters page, which means you can jump the link wherever you please.

The service works with a variety of popular blogging tools like TypePad, Blogger, and WordPress. However, LiveJournal, Facebook, and MySpace users are out of luck since these sites don't allow JavaScript from outside sites.

You can give it a spin on the names I've added after the break.

Gizmoz rolls out new face-mapping video service

We're total suckers for video products that let us use our face. A few months back, Caroline put my head on a woman's body with the launch of JibJab's Starring You service, and shortly before that, Rafe played around with Fix8, which lets you overlay live video with avatar and object overlays. Both are vastly different technologies, but the idea is the same: quick entertainment with very little effort on the part of the end user. Along the same lines, Gizmoz, which has been providing 3-D face-mapping technology to the masses since late May, is launching a … Read more

Border IDs checked without leaving car

Contrary to popular belief, not all of Japan's R&D goes into robots and Hello Kitty (or so we're told). In fact, it's not even all destined for the consumer market.

NEC, for example, has applied its technological prowess to "the world's first automated border control system that uses facial recognition technology capable of identifying people inside their automobiles," according to Pink Tentacle, and it's already being used at checkpoints between Hong Kong and Shenzhen. The biometrics system was developed to break immigration logjams in China and elsewhere, checking chip-embedded national ID … Read more
