A team of engineers from the US and Germany has developed a program called Face2Face, which allows user to change the facial expressions and replace human speech, captured on video in real-time, according to Engadget.
Videos are edited using a simple web camera that takes facial expression and voice recording. The program then applies the mimics of a controlling actor to any other person. This can be done live and pasted in the video stream. Under the actors control the face on the screen is able to answer questions, and also to simulate facial expressions.
To demonstrate the capabilities of Face2Face, developers have used video with performances by George Bush, Vladimir Putin and Donald Trump. In each case, the result looked impressive, but some man still can be seen.
So far Face2Face is not available for free use, since it is in development stage. However, its creators intend to bring a product to market in the near future.
