Supasorn Suwajanakorn generiert 3D-Modelle von Promi-Gesichtern aus Bildersammlungen und die Ergebnisse sind schon ziemlich brauchbar für allerlei Unfug, hier das Paper: What Makes Tom Hanks Look Like Tom Hanks. Die erste Iteration seiner Forschung hatte ich vor ’nem Jahr hier gepostet.

“One of the applications is in augmented reality and virtual reality,” said Ira Kemelmacher-Shlizerman, an assistant professor of computer engineering at the University of Washington, and one of the authors of a paper that is set to be presented at the International Conference on Computer Vision this month. “We’re not there yet, but our research leads to that.”

In other words, imagine if a video call didn’t just feature a person’s voice and two-dimensional face on a screen—but instead brought a projection of that person into the room with you.

We reconstruct a controllable model of a person from a large photo collection that captures his or her persona, i.e., physical appearance and behavior. The ability to operate on unstructured photo collections enables modeling a huge number of people, including celebrities and other well photographed people without requiring them to be scanned. Moreover, we show the ability to drive or puppeteer the captured person B using any other video of a different person A. In this scenario, B acts out the role of person A, but retains his/her own personality and character. Our system is based on a novel combination of 3D face reconstruction, tracking, alignment, and multi-texture modeling, applied to the puppeteering problem. We demonstrate convincing results on a large variety of celebrities derived from Internet imagery and video.
