PornHub used AI to remaster the oldest erotic films in 4K

PornHub has delved into the past to remaster some of the oldest erotic movies in existence. The Remastured project (warning: that link will lead you to some very NSFW images) used AI to restore and colorize skin flicks from as far back as 125 years ago. The porn giant harnessed machine learning and 100,000 adult images and videos to teach the AI how to colorize the films (perhaps it also learned a thing or two about how people passed the time 100 years before smartphones). Several algorithms were used to restore the films with "limited human intervention," according to PornHub. The process started by reducing noise and sharpening and contrasting images.
