Google first showed off its RAISR technology, which uses machine learning to produce high-quality versions of low-resolution images, in November last year. Now the company has published a blog post to announce that RAISR has been implemented into Google+ for Android. Google+ is used by many photographers to display high-resolution images and the move is aimed at reducing mobile data requirements, which could be particularly useful in areas with slow connections or when using data is expensive, for example when roaming. 

RAISR allows for viewing images at their (almost) full glory while reducing bandwidth requirements per image by up to 75%. Google has only just begun to apply the technology to high-resolution images in the Google+ streams of a subset of Android devices but is already processing 1 billion images per week, resulting in a total bandwidth reduction of about a third for the affected users. Google says it is planning to roll out RAISR more broadly in the coming weeks, so your data consumption might go down soon if you use Google+ frequently.
