And now, the company is open-sourcing one of these AI tools — a piece of software that underpins the Pixel’s portrait mode.

As announced in a blog post earlier this week, Google has open-sourced a lump of code name DeepLab-v3+. This is an image segmentation tool built using convolutional neural networks, or CNNs: a machine learning method that’s particularly good at analyzing visual data. Image segmentation analyzes objects within a picture, and splits them apart; dividing foreground elements from background elements.
