Google’s Pixel 2 portrait photo code is now open source

by John_A

Of all the AI-related features inside the Pixel 2 and Pixel 2 XL, the portrait mode is arguably the most impressive — Google manages to produce dramatic-looking depth-of-field effects without relying on dual cameras or other exotic hardware. And now, it’s sharing some of those secrets with the rest of the world. The company has opened up the source code for DeepLab-v3+, the AI-based image segmentation technology that helps Pixel 2 phones separate the foreground and background. It uses a neural network to detect the outlines of foreground objects, helping to classify the objects you care about in a scene while ignoring those you don’t.

This doesn’t guarantee that new phones or camera apps will take Pixel 2-quality portraits, although it does open that possibility. And really, phone photos aren’t the point. Google researchers are hoping that both academics and industry figures will use the source code to not only improve on the technology, but find uses that Google hasn’t anticipated. This could be used for object detection and many other tasks where spotting boundaries could come in handy.
