New Google technology can save us a lot of mobile data – Shifter

For now, the RAISR is only available on Google+, but the company wants to roll-out the technology more broadly.

Google has developed a technology of image compression called RAISR (Rapid and Accurate Super Image Resolution), thought to save your data plans without sacrificing the quality of the photos. The RAISR is active on Google+.

The Google+ may have failed while the social network style of Facebook, but the platform has remained popular among photographers and other groups of enthusiasts. It is possible to share high resolution pictures and quality on Google+, which can lead to a higher consumption of data on the part of those who navigate in the service. The solution is to compress the images. The Facebook makes this compression at the time of the loading of the files, and her resulting loss of quality and substantial, yet can be disguised if you shared photos with high resolution.

that Is why in Facebook we upload photos at least 2048 pixels in height and/or width, the maximum resolution supported by the social network. When viewed on the screen of a phone or on a computer monitor, the failures that resulted from the compression can go unnoticed given the size of the image.

In Google+, the photos can be shared with resolution higher than 2048 pixels, and Google will go on to use the RAISR to show large images on the phones of the users, sacrificing is not the quality but the weight of the file. Through learning machine ("machine learning" in English), the RAISR picks up a version of the image with 1/4 of the original size, expanding it to the initial dimension and applies a filter able to fool our eyes, making us believe that the low resolution version of is on par with the original variant.

Google says that the RAISR may result in savings of up to 75% in data consumption. The technology is available to Google+ users via an Android application. On the blog, where it announces the news, the company reports that the RAISR is already being applied to more than one billion images per week, and adds that he expects the "to launch this technology in a more extensive way".

anyone Who follows the series Silicon Valley can’t think of RAISR not remember the Pied Piper, a start-up dummy that uses artificial intelligence (and machine learning) to optimize images and other files. In theory, the algorithm of the Pied Piper makes the files so small that its size becomes insignificant.
