Months after rumors claimed Apple was behind the mysterious acquisition of real-time motion capture technology firm Faceshift, the Cupertino, Calif., company confirmed the purchase on Tuesday, but declined to offer details on the matter.

Apple offered its usual boilerplate statement to TechCrunch, saying it buys smaller technology companies "from time to time," but does not normally discuss plans for acquired assets. The publication said it was able to get a confirmation after finding "sources and conclusive links" to Apple's involvement.

Initial reports in September cited documents showing Faceshift was indeed purchased by an unnamed outside company. One of the new corporate directors taking over control of Faceshift's IP, at least on paper, was an attorney from Baker & McKenzie, a firm known to work with Apple on quiet takeovers.

According to TechCrunch, a number of former Faceshift employees continued on at Apple and now work out of the company's European offices.

Before being purchased by Apple, Faceshift developed powerful facial recognition software that helped power advanced motion capture technology capable of real-time, low-overhead processing. Using 3D sensors and a camera, Faceshift's tech eschews the need for traditional motion capture rigging, specifically the stick-on reference markers often seen being worn by actors in animated or CGI-heavy live action movies. Most notably, the tech was used to map human-like gestures onto the faces of certain characters in the new "Star Wars" film.

Faceshift was known for a product called Faceshift Studio, which incorporated the firm's facial recognition software with support for Maya and Unity. Consumer-facing iterations were in development for Skype, though it appears that project has been shut down.

With the Faceshift buy, Apple continues to build out its portfolio of facial recognition technologies, one of the first being Swedish firm Polar Rose in 2010. The company also acquired Israeli company PrimeSense, collaborators on Microsoft Kinect hardware and software for Xbox, in 2013 and holds multiple patents in related fields.
