‘Machine learning’ to help recover all your happy memories

By Anick Jesdanun | October 30, 2016, Sunday | Print Edition

IF you’re like many people, you have thousands of photos on your phone, long forgotten after you’ve posted a few on Instagram or Facebook.

They don’t have to stay forgotten. Apple and Google are both applying a form of artificial intelligence called “machine learning” to organize your pictures and video — and along the way, help you rediscover last year’s vacation, dinner with close friends and a casual summer outing to the park.

Apple’s tools are part of last month’s iOS 10 system update for iPhones and iPads. The Google Photos app for Apple and Android devices has a digital assistant to automatically organize these memories — and Google signaled last week that it will only get smarter. And this month, Google introduced additional features for rediscovery.

Here’s a look at how they take you down memory lane.

New Memories feature

Apple’s new Memories feature automatically generates video highlights around a theme, such as a trip or birthday party. Individual photos and snippets from video are chosen for you, as is the music, though you can change it to reflect a different mood.

This isn’t just a slideshow. There’s slow zooming and panning, reminiscent of Ken Burns historical documentaries. Some of the photos also come to life, at least on newer iPhones that automatically take three seconds of video with every photo.

When you’re ready to share, the app creates a standard movie file — so it works on Windows and Android devices, too.

For me, Apple’s app created a “Florida to Illinois” package for a three-week trip in January and one for a day trip to Philadelphia last November. But Apple goes beyond date and location. Apple created a “Together” package for shots with family over the past two years. It also created an “At The Beach” package with beach photos since 2013. Other scenic themes could include mountains, lakes and sunsets.

Apple offers up to three new Memories a day. You can create more based on photos you add to an album and generate new automated ones by scrolling down to “Related.” You can also add or delete images within Memories — in my experience, a few included mundane screenshots I had to get rid of.

Nothing will ever replace the human touch. But let’s face it, even though I keep meaning to organize my photos, I never find the time. The machine-generated selections aren’t necessarily ones I’d choose myself, but with a small amount of tweaking, they’re presentable and will tide me over until I get around to catching up manually ... someday.

Enhancing photos, video

Google Photos has been at this longer and offers more types of packages. With collages, Google combines smaller versions of several shots into one layout. Animations combine a bunch of photos taken in succession so that they resemble as a moving image. Unlike typical “GIF” animation files, Google applies its magic to align successive shots, so buildings and bridges look steady — without the shake common with handheld video. Google also offers albums and video highlights, though without the Ken Burns effect.

Google’s Assistant generates much of this for you automatically. You can edit auto-generated albums and video highlights, but not collages or animation — although you can create your own from scratch. (That does defeat the purpose of letting the robots do the work, though.)

Sharing is easy and doesn’t require recipients to have Google Photos.

The results vary in quality. I tend to take several shots of the same subject, just in case some are blurry. Yet I get collages and animations out of those repetitive shots. The albums and video highlights I got are grouped by location and date, though Google says it will be doing more with themes , such as following a kid growing up.

Most of my computer-generated creations are animations and collages. As with Apple, Google’s choices aren’t necessarily ones I’d make, if only I had the time. But some are good enough that I look forward to alerts for new ones to check out.
