For Valentine's Day, Google is adding animated hearts to photos of hugging and kissing on Google+.
"Just upload a photo of kissing or hugging, and Google Photos will add hearts automatically," said Google+ photo team member Vincent Mo in a Google+ post Thursday night.
Google already throws a lot of server horsepower at photos shared on its social network, automatically editing them for better tonality and smoother skin, but its "auto-awesome" technology also identifies subject matter deemed suitable for seasonal special effects. During the holidays, the company added snowflakes to snow scenes and sparkling to Christmas trees.
As with its earlier effects along these lines, Google does the detection and editing automatically, then leaves it to you to decide what to do with it.
"Share the photo with someone special, or keep it for your eyes only," said Erik Murphy-Chutorian, whose team added the feature.
The technology is clever -- but as snowflakes over desert scenes showed, it's also fallible. Feel free to share links in comments below to good examples or misfires.
