Signal Processing for 3D Imaging And Virtual Reality

  1. Content type: Research Article

    This paper studies a new method for three-dimensional (3D) facial model adaptation and its integration into a text-to-speech (TTS) system. The 3D facial adaptation requires a set of two orthogonal views of the...
