Meet the floating city of the future.

The world is about to see a mind-blowing demographic situation that will be a first in human history: There are about to be more elderly people than young children.

For some time now, demographers and economists have observed that the proportion of elderly adults around the world is rising, while the proportion of younger children is falling.

But within a few years, just before 2020, adults aged 65 and over will begin to outnumber children under the age of 5 among the global population, according to a chart shared by a Bank of America Merrill Lynch team led by Beijia Ma, citing an earlier report from the US Census Bureau.

or chroma keying, is a special effects / post-production technique for compositing (layering) two images or video streams together based on color hues (chroma range). The technique has been used heavily in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture and videogame industries.

What if you could alter a video of anyone to emulate facial and mouth movements that never existed in the source video—by yourself, at home, using a cheap webcam?

Meet Face2Face. Using RGB input from one video and mapped pixels from a second video, manipulating someone’s face—including distinct facial and mouth movements—has become incredibly easy. A team of researchers recently released a video showing what this looks like in real-time. While the method is still imperfect, it has major implications for future online content.

According to the team’s publication: “Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in a photo-realistic fashion.”
