Puppenspiel der Gesichter

Jemandem Worte in den Mund legen - ist das mittlerweile möglich?

(PresseBox) (Saarbrücken, )
Eine Gruppe von Wissenschaftlern aus Erlangen, Stanford und Saarbrücken kann Mimik und Lippenbewegungen einer Person in Echtzeit auf das Video-Signal einer anderen Person übertragen; Gestik und Kopfbewegungen der Ursprungsperson bleiben dabei unverändert. Die entwickelten Algorithmen sind dabei so effizient, dass die Rechenleistung von Standard-Hardware ausreichend ist.

Beide Personen werden von einer Kamera gefilmt, die zusätzlich zu normalen Bildinformationen auch Tiefendaten aufnimmt. Solche Kameras (z.B. Microsoft Kinect TM) vermessen also zusätzlich die Entfernung jedes Bildpunktes zur Szene. Basierend auf diesen Daten, werden in einem Vorverarbeitungsschritt, für beide Personen die Parameter eines Gesichtsmodells geschätzt, so dass Kopfgeometrie und Reflektanz in einer mathematischen Ycvtksxsgtwr qemsgiwcj.
