    Abstract: An omni-directional camera (a 360 degree camera) is proposed with an integrated microphone array. The primary application for such a camera is videoconferencing and meeting recording, and the device is designed to be placed on a meeting room table. The microphone array is in a planar configuration, and the microphones are located as close to the desktop as possible to eliminate sound reflections from the table. The camera is connected to the microphone array base with a thin cylindrical rod, which is acoustically invisible to the microphone array for the frequency range [50-4000] Hz. This provides a direct path from the person talking to all of the microphones in the array, and can therefore be used for sound source localization (determining the location of the talker) and beam-forming (improving the sound quality of the talker by filtering only sound from a particular direction). The camera array is elevated from the table to provide a near frontal viewpoint of the meeting participants.

    Abstract: Automatic detection and tracking of multiple individuals includes receiving a frame of video and/or audio content and identifying a candidate area for a new face region in the frame. One or more hierarchical verification levels are used to verify whether a human face is in the candidate area, and an indication made that the candidate area includes a face if the one or more hierarchical verification levels verify that a human face is in the candidate area. A plurality of audio and/or video cues are used to track each verified face in the video content from frame to frame.

    Abstract: Systems and methods are disclosed that facilitate real-time information exchange in a multimedia conferencing environment (500,800). Data Client(s) (508,806) facilitate data collaboration between users and are maintained separately from audio/video (AV) Clients (512) that provide real-time communication functionality. Data Clients can be remotely located with respect to one another and with respect to a server (502,804). A remote user Stand-in Device (808) can be provided that comprises a display (810) to present a remote user to local users, a digital automatic pan/tilt/zoom camera (522) to capture imagery in, for example, a conference room (802) and provide real-time information to an AV Client in a remote office (818a,...,818n), and a microphone array (526) that can similarly provide real-time audio information from the conference room (802) to an AV Client in the remote office. The invention further facilitates file transfer and presentation broadcast between Data Clients in a single location or in a plurality of disparate locations.
