In a bid to save you precious mobile data, Google has developed a technique that improves image quality without taking up more bandwidth. Entitled RASIR (Rapid and Accurate Super Image Resolution) this impressive software quickly reads large photos and manages to replicate them using a quarter of the pixels.

RASIR achieves this by analyzing both low and high-quality versions of the same image. As it reads the image, it learns from the superior version and applies filters to its low-res counterpart that simulate extra detail, creating a convincing data-friendly replica of the original high-res photo.
