Google’s ‘Frankenphone’ Helped Gather Training Data for Portrait Mode on the Pixel 3

Google has been leading the charge of computational photography in smartphones ever since the first Pixel, when it introduced its HDR+ technology. Since then, the search giant has not looked back and with the introduction of the Pixel 3 ₹ 59,999 series, it’s evident that it’s miles ahead of the competition when it comes to camera software. The Pixel 3 and Pixel 3 XL ₹ 80,998 are the current flagship Android smartphones from Google and have some of the best cameras in the business, largely thanks to some new developments to its Portrait mode algorithm and new features like Night Sight and Super Res Zoom.

Earlier this week, Gadgets 360 was privy to a media roundtable with Marc Levoy, a distinguished engineer at Google’s research lab, where he talked in detail about how these new technologies were developed for the new smartphones.

In the Pixel 3 (Review) series, Google has revamped Portrait mode, as it moves away from stereo-based depth maps to a learning-based technique that uses machine learning to deliver more accurate edge detection and a more realistic background blur. Google has also released a blog post which details this but here’s a quick summary of how it works and what’s changed from Portrait mode on the Pixel 2 ₹ 28,879 (Review).
