Apple to bring face recognition to iOS 5

Apple’s iOS 5 will have built-in facial recognition capabilities. Better yet, Apple isn’t planning on simply using the technology to power a single feature. Instead, it will release it as an open API for developers, bringing easy integration of face recognition to the App Store.

9to5 Mac put the pieces together, finding that Apple has put to use the 2010 acquisition of Swedish facial recognition algorithm specialist Polar Rose. While it sounds like the name of a Sting album, Polar Rose has an impressive portfolio of developments, including Recognizr, a social media linking app co-developed with TAT that recognizes users and displays their network profiles on-screen. Check out the demo video below.

The tech is already available in OS X Lion as Photo Booth, which uses facial recognition to accurately manipulate user’s photos into all kinds of wacky final products. The feature has been included in all manner of Windows webcams and whatnot for awhile now, but has only just trickled over to the Apple ecosystem. It’s unclear if Apple with bring Photo Booth itself over to iOS, but once the API is released to developers, expect photo manipulating apps to blossom into flashlight app-like numbers.

9to5 Mac dove into the APIs, and found two related to the Polar Rose technology. One, called CIFaceFeature, can determine where a person’s mouth and eyes are on a photo. The second, CIDetector, is an operating resource for that “processes images for face detection” which possibly would be used for video.

So what’s it all mean? Photo manipulation aside, Recognizr shows off a likely route facial recognition will take. Using your face as your business card and link to online profile is more instant than other methods, and is great if your name is hard to spell. Of course, it’s also cause for privacy advocates to start chattering. Although using facial recognition software to glean information off someone will be limited to whomever lists their profile with a service like Recognizr (until Facebook decides to get involved), it does open up a new avenue for privacy discussion that Apple is going to have to deal with as they prep to launch the iPhone 5.

Apple’s latest iPhone SE can be yours for $149 today

The Apple iPhone SE (2022) being held in a mans hand.

Alongside the many Prime Day deals that Amazon has been running, Walmart has also offered its own sale in the form of Walmart+ Week. One of the best deals there is on the third-generation iPhone SE for just $149. It's a huge saving of $230 compared to the original price of $379 although there is a catch -- the phone is locked to a Straight Talk prepaid subscription. Still, if that isn't an issue for you, this is a super sweet deal. You're going to need to be fast though as with Prime Day running to a close in a matter of hours, it's also likely that deals like these will end soon too. Here's what to expect from it.

Why you should buy the third-generation Apple iPhone SE
The third-generation Apple iPhone SE, which was released in March 2022, is powered by Apple's A15 Bionic chip -- the same one that you'll find in the iPhone 13 and the iPhone 14. That means the Apple iPhone SE 2022 is pretty powerful for its price, with snappy performance when you launch even the most demanding apps and when you're multitasking between them. The device is also equipped with a 4.7-inch Retina HD display, which may be small compared to the screens of other modern smartphones, but it makes up for the lack of size with excellent color accuracy and overall high quality.

How to turn a Live Photo into a video on your iPhone

Live Photo to video with hand holding iPhone.

Live Photos is a fun feature Apple brought to the iPhone 6s many years ago, turning static photos into three-second clips by capturing what happens in the 1.5-second interval before and after you tap the shutter button. This feature has been a staple of every iPhone model since then, and even if you're new to the iPhone, you've likely already used it already since it's turned on by default — you have to take specific steps to disable it if you want to go back to taking normal snapshots.

There aren't any significant downsides to leaving Live Photos enabled. You can share them as a normal, static photo just like other image, and while they will take up a bit more space on your iPhone, that's not as significant as it once was, thanks to Apple's switch to the more efficient HEIC format in 2017. While Live Photos could once grow nearly twice as large as the same static JPEG, today you'll more typically see only a 25% difference, on average.

Even though Apple finally added support for home screen widgets a few years ago, it wasn't until iOS 16 that these finally made it onto your lock screen, allowing you to quickly see everything from the weather to your to-do list, upcoming appointments, and more at a glance — all without unlocking your iPhone.
