Creating a speech-enabled avatar from a single photograph

總結: Lead Inventors: Shree K. Nayar, Ph.D.Problem or Unmet Need:While computer graphics technology has progressed dramatically over the past couple years, there remains a pressing need to develop human face avatars, which can realistically present and animate a person's face on screen. The current available approaches to this problem have several limitations, such as being not completely accurate in both animation and appearance, and requiring large amounts of seed data to produce a believable presentation. Accordingly, it has been difficult to create an avatar that looks and sounds as if it was produced by a human face that is being recorded by a video camera. Thus, creating speech-enabled avatars of faces that provide realistic facial motion from text or speech inputs represents a worthwhile endeavor. This technology is a framework for creating speech-enabled 2D or 3D avatars from just a photograph or a single stereo image of a face respectively. The avatar contemplated can be animated using text or speech input and a novel motion synthesis algorithm. The approach proposed here can significantly enhance the user experience and create new modes of interactive applications for users.

技術優勢: The technology described here can be used to develop more realistic avatars, which can be animated using text or speech input This method can be applied to 2- or 3-D environments

技術應用: Sufficiently accurate speech-enabled avatars can have multiple applications, predominately related to the user experience in various contexts: Communications: This technology can be used in video conferencing applications and generating avatars for social networking or web profiles. Advertising: This approach can create interacting avatars used in web-based or physical ads. Gaming: This method can be used to provide better gaming experience by creating more realistic avatars. Information Retrieval: The product can be used as an interface to extract information from a kiosk at a number of locations

詳細技術說明: This technology is a framework for creating speech-enabled 2D or 3D avatars from just a photograph or a single stereo image of a face respectively. The avatar contemplated can be animated using text or speech input and a novel motion synthesis ...
