Google has open-sourced an AI tool that helps phones shoot pictures in portrait mode

in news •  2 years ago 


Google’s Pixel phone has one hell of a camera, and one of the reasons for this is AI. Google has used its machine learning talent to squeeze better images out of a tiny smartphone lens, including its portrait mode shots, with blurred backgrounds and pin-sharp subjects

Now, Google has open-sourced a lump of code named DeepLab-v3+ that it says will help others recreate the same effect. (Although, this is not the same tech that Google itself uses in the Pixel phones — see the correction note at the bottom of the article.) DeepLab-v3+ 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. This can then be used to create ‘bokeh’ style photographs

As Google software engineers Liang-Chieh Chen and Yukun Zhu explain, image segmentation has improved rapidly with the recent deep-learning boom, reaching “accuracy levels that were hard to imagine even five years [ago].” The company says it hopes that by publicly sharing the system “other groups in academia and industry [will be able] to reproduce and further improve” on Google’s work.

At the very least, opening up this piece of software to the community should help app developers who need some lickety-split image segmentation, just like Google does it.

Mention about Google... nah... don't ever mention that lier and corrupt organization

Good post my buddy

hmmm, not sure why this is posted in smartcash, nothing about it is smart.

lol 😁 😁 , this made me burst into a pool of laughter, nothing indeed
