Systems And Methods For Providing Personal Video Services

摘要

Systems and methods for processing video are provided. Video compression schemes are provided to reduce the number of bits required to store and transmit digital media in video conferencing or videoblogging applications. A photorealistic avatar representation of a video conference participant is created. The avatar representation can be based on portions of a video stream that depict the conference participant. A face detector is used to identify, track and classify the face. Object models including density, structure, deformation, appearance and illumination models are created based on the detected face. An object based video compression algorithm, which uses machine learning face detection techniques, creates the photorealistic avatar representation from parameters derived from the density, structure, deformation, appearance and illumination models.

主权项

1. A method of video conferencing, the method comprising the steps of:
detecting a human face of a video conference participant depicted in portions of a video stream; creating by explicitly modeling one or more explicit object models to model the face of the video conference participant; generating one or more implicit object models relative to parameters obtained from the explicit object models to facilitate creation of a compact encoding of the video conference participant's face; and using the implicit object models, creating a photorealistic avatar representation of the video conference participant.
