Recovering “Lost Dimensions” of Images, Video

Fascinating idea I could have used long ago.  Projections, for example, from advertising copy, archived and needed for reapplication. 

Recovering “Lost Dimensions” of Images, Video
MIT News   Rob Matheson

Researchers at the Massachusetts Institute of Technology (MIT) have developed a model that recovers valuable data lost from images and video that have been "collapsed" into lower dimensions. Captured visual data often collapses data of multiple dimensions of time and space into one or two dimensions called "projections." The researchers created a "visual deprojection" model that uses a neural network to learn patterns that match low-dimensional projections to their original higher-dimensional images and videos. The model takes in new projections and uses what it has learned to recreate the original data. During testing, the model synthesized accurate video frames showing people walking by extracting information from single-one-dimensional lines. The model also recovered video frames from single, motion-blurred projections of digits moving around a screen. ..."
