Facebook and Facial Recognition: An Obvious Marriage?
0The science of recognizing a face and the intelligence to recognize the same one twice. Or a million times. That’s one of 2009′s crowning technological achievements. Oh, sure, there have been facial recognition algorithms around for years, but up until this year, we haven’t had that feature on a mainstream consumer level. Within the past year, we’ve seen point-and-shoot digital cameras receive the ability to focus on individual faces in a frame and some of those cameras can even detect whether or not you’re smiling (and summarily refuse to snap the photo!). Standalone desktop applications like Apple iPhoto and Google Picasa will now scan your entire photo library for faces and once you’ve given the software some training, it’ll auto-detect and tag the mugs of family, friends, and maybe even your dog. In fact, Google’s online photo catalog software, Picasa Web Albums, has been doing the same thing for awhile as well. It’s a feature that makes cataloging photos much, much easier. No longer must you rely on finding an exact folder or using a non-smart desktop search tool to find the person you’re looking for. As long as you can remember their name, you can find their face.
For as long as most of us can remember, Facebook has allowed photo tagging. Upload your photos, click a cross-hair across a person’s face, and type in their name. If they’re using Facebook, it’ll link directly to their profile page and notify them that their face is now floating around the ‘net for any of their friends to see. A cool feature, very informative, and a stalker’s dream. But one thing that’s been bugging me for awhile is: why stop there?
Facebook, no doubt, has tens of petabytes worth of data stored across its servers and much of that is photo related. People upload terabytes worth of photos every day. Why isn’t Facebook using all that meta information to make your life easier? Imagine uploading 75 pictures of you and your friends from last week’s party. Facebook would then analyze each photo, tag everyone it recognizes from your friends list, and give you a confirmation page to adjust any of the tags. My guess is that the system wouldn’t even require training from the user as it could pull aggregate data from profile pictures and other tagged photos in order to make the whole process incredibly quick and easy. The question isn’t if they could do this, it’s why have they not?
Two reasons come immediately to mind, the first being that of privacy concerns. Suddenly you’ve turned Facebook into a huge searchable photo database that could make any law enforcement officer’s day by providing thousands of images and demographics of people not available in government or criminal databases. You’d also be presenting yourself as a target for some dangerous information leakage if Facebook were ever breached. This concern, I believe, is mostly without a logical base. Users continue to manually tag friends anyway and unless you disable the tagging system altogether, privacy will always be a concern.
The second potential issue is one of raw processing power. For instance, it took my beefy ThinkPad about 4 hours to sort through my collection of approximately 25,000 photos. That’s one dual core CPU’s near best effort since the average processor utilization was somewhere around 70%. I’m guessing Picasa was leaving some of the CPU free so that the machine didn’t slow to a complete crawl. Imagine then the billions of photos stored across Facebook servers. The company would need to create a system to process every single photo containing a face, match already associated tags, and create a massive database containing the results. This process would require not only a lot of time, but much additional storage space as well. Fortunately, storage is cheap these days–unfortunately the required number of extra CPUs and RAM modules are not.
As a side note, there was a Facebook Application released in the not-too-distant past allowing users to scan their photos for faces, but my guess is that without widespread use (and some major venture capital), the corresponding company and software didn’t get too far.
Ultimately, I think facial recognition is something that Facebook should and will eventually add to it’s service. My guess is that this feature is already in the works; however, Facebook usually holds close its cards until they’re ready for some sort of official release plan. Keep watching Facebook for any new information, and of course, you’ll find the details here as well when the announcement does arrive. My prediction? We’ll see something emerge by the end of 2010.

Real-time screen capture for free
2Stumbled across this pretty sweet software product today while doing some research. CamStudio is a free, open-source (GPL licensed) screen capture application for Windows PCs. It can capture both audio and video simultaneously, allowing the user to record voice annotations along with the current action on the screen.
While CamStudio records everything in a proprietary codec, it is capable of exporting to both high-quality AVI and smaller Adobe Flash SWF files for web streaming purposes.
Their website is a little gimmicky looking and not incredibly easy to use, but scrolling halfway down the page will bring you to the product download links.

Why we need multiple web browsers
0Ask any ten different people what their favorite browser is and it’s possible you might possibly end up with ten completely different opinions. That’s because these days browsers are a dime a dozen and it’s mostly up to the consumer which browser he or she uses. Major players in today’s market include Internet Explorer, Firefox, Google Chrome, Safari, and Opera. With the exception of Internet Explorer, all of these browsers are more or less available for any OS you use. But which one is the right browser? Which is the best? That question has become the object of many a debate and a post like this can’t settle it once and for all–especially with the daily changing face of technology. But although some web developers (designers especially) would like to have only one global browser (or at least force all browsers to use the same rendering engine), there is actually good reason in having a diverse market.
The hating of Internet Explorer
There’s no question that Microsoft’s Internet Explorer remains the dominant browser on the market at this time. Between the number of users surfing with version 6, 7, or 8, well over 50% of the world is still IE-centric. Yet you’ll find developers, designers, and consumers have developed the widespread opinion that Internet Explorer is bad. Period. This, simply, is not true.
Back when Internet Explorer 6 was released with Windows XP in 2001, it really began to change the face of the Internet itself. We started to see a lot more plugins being written to make websites more “dynamic.” Broadband connections were seriously beginning to take off and the phenomenon we now know as Google was setting the stage to become one of the Internet’s dominating forces. IE6 was compliant with HTML4 web standards, made possible the widespread use of CSS, and was fast and light. As an integral part of the Windows operating system, it took full advantage of certain performance enhancements. IE6, as much as it is despised now for it’s lack of HTML standards support, is really partially responsible for getting us where we are today. Versions 7 and 8 may have been Microsoft’s catch-up game, but as far as standards-compliant browsers go, things have come a long way since 2001.
Enter Firefox
The next major market player was officially introduced in 2005 by Mozilla, creator of Firefox’s ancestors Mozilla Suite and Netscape. Version 1.0 was slow to catch on outside the developer community, but many saw it as a good future competitor to Microsoft’s browser market domination. Firefox re-defined the way we use the Internet by successfully introducing tabbed-browsing for the first time. Some would correctly argue that Opera was the first to implement this feature, but Opera’s failure to capture significant market-share makes Firefox tabbed-browsing’s rightful ancestor. Version 2.0 saw a small spike in usage and by the time version 3.0 arrived in mid-2008, Firefox had gained significant hold on over 30% of Internet users. Firefox uses the Gecko rendering engine and has been influential in setting the bar for browsers being standards compliant.
Webkit: Safari and Chrome
Apple’s Safari and Google’s Chrome are even more recent additions to the browser community. Together they have further upped the ante for browser competition. Until Safari 3.0 was released, the browser was pretty unsuccessful. All but the most loyal Mac users immediately downloaded Firefox upon getting a new computer. Version 3.0 was the first truly successful implementation of Safari as a mainstream browser and version 4.0 may receive relatively equal use to Firefox on the OS X platform. As a competitor to other browsers on the Microsoft Windows platform, Safari has largely failed to capture any sort of audience.
The other Webkit-equipped browser is Google Chrome. It’s announcement was a surprise to many and it’s subsequent popularity has been an even greater shock. (I’m actually using Chrome to write this post). It remains to be seen if the trend will continue, especially as Google prepares to release their own Chrome-based operating system. Safari and Chrome contain very similar feature sets.
The Webkit and Mozilla Gecko 1.9 rendering engines are two of the first to officially support a preliminary implementation of CSS3 attributes. While Microsoft has been playing catch-up, Apple, Google, and Mozilla have been pushing the envelope by rewriting their Javascript engines, introducing new browser features, and preparing to support future Internet standards. In fact, Firefox 3.5 is the first browser to support HTML 5. It includes powerful new architecture to support native HTML 5 video and local persistent storage for web applications.
We can see from the history of these various browsers that innovation drives the web. The W3C will often ratify new standards based on implementations completed by browser vendors–especially if a feature is supported across multiple browsers. We can only hope that the market-share will continue to even out as it has done up to this point. With each manufacturer seeking to bring new features to market before its competitors, we will continue to use innovative technologies in our daily online routines.
