Everyone has seen in the movies how people continuously zoom in on the portion of a frame from a video surveillance footage to see the details that were obviously impossible to obtain. Believe it or not, today’s technology may actually make this type of operations a reality. One of the image processing tasks under investigation and developed at EPFL for the AdMiRe project is Super Resolution. Thanks to the recent advances in the field of artificial intelligence and multimedia signal processing, now we can zoom into images and video by while convincingly reconstructing the missing details.

Researchers from Multimedia Signal Processing Group (MMSPG) at EPFL presented the latest results on compressed-domain super resolution at the 91st JPEG Standardization Meeting. JPEG stands for Joint Photographic Experts Group that is a joint working group of the International Telecommunication Union (ITU), the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) where international experts discuss and develop new specifications in the field of imaging.
