摘要： A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.

摘要： Upon receiving a continuous presence video image, an endpoint of a videoconference may identify its self image and replace the self image with other video data, including an alternate video image from another endpoint or a background color. Embedded markers may be placed in a continuous presence video image corresponding to the endpoint. The embedded markers identify the location of the self image of the endpoint in the continuous presence video image. The embedded markers may be inserted by the endpoint or a multipoint control unit serving the endpoint.

摘要： A videoconferencing system for determining alignment information for images captured by two or more cameras is disclosed. The videoconferencing system can include a plurality of endpoints and at least one control unit (CU) such as a multipoint control unit (MCU), for example. An endpoint can include a plurality of cameras and at least one projector. The projector is used to project a pattern at the near end site, which pattern is captured by the plurality of cameras. The image frames produced by the cameras are processed to determine the identity and location coordinates of the images of the projected patterns. The location coordinates can be used as reference points to be used by applications such as telepresence, 3D videoconferencing, and morphing.
