In the early 90's I was working in early streamed digital video. One of the projects was a history of aviation documentary. The original negatives of early flight, including the original Wright Brothers flights are lost. But in many cases paper print outs of them remain. Before copyright was extended to film, to get a copyright a film had to be printed to paper. These paper print outs are all that remain. But this being the early 90's, there was no machine learning nor a formal field of computer vision as we know it now. We painstakingly scanned the thousands of feet of printed film, and reconstructed them as CLUT-127 (color look up table) animations. I seem to remember that project got streaming media awards of some sort. It was a long time ago.
