Images with low quality spell doom not only for your photographic skills, but also for the numerous medical diagnosis that doctors do using scanned images of your body. Now, researchers have developed a new algorithm that can denoise  such bad quality images in a few seconds. Running on advanced processing units called graphical processing units, the algorithm promises to be a new hope in the rising field medical imaging, satellite imaging and other fields dealing with high resolution images.
