GPU Accelerated Realtime Skin Smoothing Algorithms Make Actors Look Perfect 138

dryriver writes: A recent Guardian article about the need for actors and celebrities -- male and female -- to look their best in a high-definition media world ended on the note that several low-profile Los Angeles VFX outfits specialize in "beautifying actors" in movies, TV shows and video ads. They reportedly use a software named "Beauty Box," resulting in films and other motion content that are -- for lack of a better term -- "motion Photoshopped." After some investigating, it turns out that "Beauty Box" is a sophisticated CUDA and OpenGL accelerated skin-smoothing plugin for many popular video production software that not only smooths even terribly rough or wrinkly looking skin effectively, but also suppresses skin spots, blemishes, scars, acne or freckles in realtime, or near realtime, using the video processing capabilities of modern GPUs.

The product's short demo reel is here with a few examples. Everybody knows about photoshopped celebrities in an Instagram world, and in the print magazine world that came long before it, but far fewer people seem to realize that the near-perfect actor, celebrity, or model skin you see in high-budget productions is often the result of "digital makeup" -- if you were to stand next to the person being filmed in real life, you'd see far more ordinary or aged skin from the near-perfection that is visible on the big screen or little screen. The fact that the algorithms are realtime capable also means that they may already be being used for live television broadcasts without anyone noticing, particularly in HD and 4K resolution broadcasts. The question, as was the case with photoshopped magazine fashion models 25 years ago, is whether the technology creates an unrealistic expectation of having to have "perfectly smooth looking" skin to look attractive, particularly in people who are past their teenage years.

        Apparently the best predictor of electoral success is candidate appearance (not money spent). So many people DO base their vote on zit counts. Although beautifying might not be the best idea for political ads. The predictor for US presidential elections was the candidate who looked "most presidential," which might not be the same as "youngest" or "prettiest."

      Let's be realistic here. Any amount of digital manipulation isn't going to change the shock value once you meet the actor or actress in meatspace. They're all going to look different/look older/look like shit by comparison.

      And the fact that photo manipulation is still alive and well after decades tells you the popularity in which video manipulation will be welcomed with open arms. The world is full of lies, and people love it.

      • The next step should be to virtualize the concept of "celebrities" and just completely regenerate the appearance of the actors. So a filmmaker could hire anyone for the role, based solely on their ability to perform, and then switch their face and appearance in post-production to match the "star" of the film who doesn't actually exist.

        There are virtual celebrities like Hatsune Miku [wikipedia.org], but in the future they will look like real people, only perfect.

      What's the point of high res capture if you're just going to muddy the image in post processing?

      In photography, the basic algorithm is to use a high-pass filter to identify high-contrast regions (places with lots of edges. Turn that into a mask and invert it. Apply a blurring algorithm to the picture, using the mask to exempt the high-contrast parts of the pic (places with lots of edges.) The final result is a pic where low-contrast surfaces (like skin and sky and blurred backgrounds) are blurred, but high-contrast edges which contain detail are untouched.

      I never liked doing it (I prefer realistic photos), but it was sometimes necessary to counter a sharpening algorithm run across the entire picture, and prevent skin blemishes from being exaggerated. Also, I found that if I first showed my female friends their photo after running it through the above algorithm, they were much less likely to threaten to kill me if I ever released that photo to the public. Who says flattery never got you anywhere?

    • If the resolution of movies is so high that they are essentially applying a blur filter everywher

      It is not a blur filter, and it is not being applied "everywhere". Only on skin. More specifically, only on the skin of the good people. The villains will still have bad complexions.

    • If the resolution of movies is so high that they are essentially applying a blur filter everywher, then maybe we should back off the higher resolutions. What's the point of high res capture if you're just going to muddy the image in post processing?

      I suppose one point is that there are other things in a scene besides the actors' faces. Higher resolution increases the immersive impact of the entire image.

      And let's not dismiss the possibility that the art will adapt to the medium as it often has in the past (not the other way around). Maybe higher-res images of actors faces, blemishes and all, will become less of an issue if filmmakers, actors, makeup artists use high-res to give us better visual storytelling.

    • One thing to recall is that the "close up" is an extremely artificial way of viewing someone. It does not exist in real life. Do you ever get inches from someone's face while they are talking (without getting smacked good and proper)?

      So doing a close-up in 8K with an actual human is going to have very unfortunate consequences unless enhancement if used, and we are used to that and expect it - we call it "make-up". But at sufficiently high resolution even physical make-up probably can't cut it.

      At CES this year they demoed a special applicator that uses something like an inkjet print head and a high speed camera to apply makeup to just the pores and imperfections on your face, smoothing your skin out and making you look younger in a fairly natural way. It didn't look like heavy foundation, it was the kind of thing that you would need an expensive makeup artist for, but easy to apply in a minute or two yourself.

    Does it compound the effect of makeup so some actress in her late 40s can still get a lead role? Or is it one or the other, meaning that a lot of makeup artists will be out of work once this tech matures.
