Google's Pixel 2 portrait photo code is now open source (update: not quite)
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+, an AI-based image segmentation technology similar to that which 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.
