Abstract:
Systems and methods are described for detecting and remedying potential incongruence in a video conference. A camera of a video conferencing system may capture video images of a conference room. A processor of the video conferencing system may identify locations of a plurality of participants within an image plane of a video image. Using face and shape detection, a location of a center point of each identified participant's torso may be calculated. A region of congruence bounded by key parallax lines may be calculated, the key parallax lines being a subset of all parallax lines running through the center points of each identified participant. When the audio device location is not within the region of congruence, audio captured by an audio device may be adjusted to reduce effects of incongruence when the captured audio is replayed at a far end of the video conference.

Claim (Index 13):
A method for at least partially ambiguating spatial audio cues in audio in response to determining that incongruence may be present, the method comprising:\n capturing, by a camera of a video conferencing system, video images of a conference room; capturing, by an audio device, an audio stream from the conference room; determining, by a processor of the video conferencing system, that potential incongruence present in far end play back of the captured video images together with playback of the audio stream, the potential incongruence being determined based on a location of the audio device within the conference room; and filtering, by the processor, the captured audio stream in response to the determining that potential incongruence is present, the filtering comprising:\n decoding the captured audio stream into a plurality of channels, the plurality of channels having a structured spatial relationship; \n assigning random phase values that are band-limited to each of the plurality of channels to modify the captured audio stream; \n constructing filters by interpolating a full filter response between the assigned random phase values; and \n applying the constructed filters to the captured audio stream to provide an ambiguated audio stream corresponding to the captured audio stream.
