Google has shown how RAISR’s engineers have done it, and is able to deal with the upscaling of images. A machine learning system can do this very effectively, reproducing pixels in higher resolution.
Just a few years ago, the image on monitors was displayed up to 1920 x 1080 pixels and no one even assumed that it could be much higher in the future. Currently, even in smartphones we have 2K screens, the standard has already become 4K displays, and manufacturers are preparing to launch 8K screens.
This brings with it the need to develop completely new technologies for upscaling materials such as photographs to fit them into new screens. Otherwise, the ultra high resolution displays will look very poor. In this case, it is not enough simply to enlarge, because then we get a blurred image.
However, Google has the solution to this problem in the form of RAISR (Rapid and Accurate Image Super-Resolution). This is a technology created specifically for upscaling photos that beats the head of currently used methods. It uses machine learning so that it can reproduce every pixel of the image in higher resolution. So the end result is very close to the original.
