Google RAISR Intelligently Makes Low-Res Images High Quality. By using machine learning images can be up to 75 percent smaller without losing their detail.

The researchers took 15 images made with low doses of X-ray radiation, and used a new software to create a high resolution one from them, a process known as "super-resolution".

We also know anecdotally that there are lots of different techniques that people can use as investigative tools to improve low-quality images, such as manipulating brightness. Our standardized face ...
