## Транскрипт

### Segment 1 (00:00 - 05:00) []

Dear Fellow Scholars, this is Two Minute  Papers with Dr. Károly Zsolnai-Fehér. Today we are going to make the Mona Lisa and  other fictional characters come to life through   this DeepFake technology that is able to create  more detailed videos than previous techniques. So, what are DeepFakes? Simple, we record a  video of ourselves, as you see me over here   doing just that, and with this, we can make  a different person speak. What you see here   is my favorite DeepFake application where  I became these movie characters and tried   to make them come alive. Ideally, expressions, eye  movements and other gestures are also transferred. Some of them even work for animation movie  characters too. Absolutely lovely. This can   and will create filmmaking much more accessible  for all of us, which I absolutely love. Also,   when it comes to real people, just imagine how  cool it would be to create a more smiling version   of an actor without actually having to re-record  the scene. Or maybe even make legendary actors   appear in a new movie. The band Abba is already  doing these virtual concerts where they appear   as their younger selves, which is a true  triumph of technology. What a time to be alive! Now, if you look at these results, these are  absolutely amazing, but the resolution of the   outputs is not the greatest. They don’t seem to  have enough fine details to look so convincing.    And here is where this new paper comes into play.    Now, hold on to your papers and have a look at  this. Wow. Oh my! Yes, you are seeing correctly,   the authors claim that these are the first one  megapixel resolution deepfakes out there. This   means that they showcase considerably more  detail than the previous ones. I love these,   the amount of detail compared to  previous works is simply stunning. But, as you see, these are not perfect by any  means. There is a price to be paid for these   results. And the price is that we need to trade  some temporal coherence for these extra pixels.    What does that mean? It means that as  we move from one image to the next one,   the algorithm does not have a perfect memory of  what it had done before, and therefore some of   these jarring artifacts will appear. Now,  you are all experienced Fellow Scholars,   so here, you know that we have to invoke The  First Law Of Papers, which says that research   is a process. Do not look at where we are, look  at where we will be two more papers down the line. So, megapixel results huh? How  long do we have to wait for these?    Well, if you have been holding on to your papers  so far, now, squeeze that paper because these   somewhat reduced examples work in real time. This  means that we can point a camera at ourselves,   do our thing, and see ourselves become  these people on our screens in real time. Now, I love the film directing  aspect of these videos, and also,   I am super excited for us to be able to even  put ourselves into a virtual world. And clearly,   there are also people who are less interested in  these amazing applications with these techniques.    To make sure that we are prepared  and everyone knows about this,   I am trying my best to teach political decision  makers from all around the world to make sure   that they can make the best decisions for  all of us. And I do this free of charge. As   any self-respecting Fellow Scholar would do,  you can see me holding on to my papers here   at a NATO conference. At such a conference, I  often tell these political decision makers that   DeepFake detectors also exist, how reliable  they are, what the key issues are, and more. So, what do you think? What actor  or musician would you like to see   revived this way? Prince or Robin Williams  anyone? Let me know in the comments below!
