Described are multiple cameras in a conference room, each pointed in a different direction. A primary camera includes a microphone array to perform sound source localization (SSL). The SSL is used in combination with a video image to identify the speaker from among multiple individuals that appear in the video image. Pose information of the speaker is developed. Pose information of each individual identified in each other camera is developed. The speaker pose information is compared to the pose information of the individuals from the other cameras. The best match for each other camera is selected as the speaker in that camera. The speaker views of each camera are compared to determine the speaker view with the most frontal view of the speaker. That camera is selected to provide the video for provision to the far end.

Matching active speaker pose between two cameras

A system for preventing private image data captured at an endpoint from being shared during a videoconference is provided. A user can select three-dimensional regions which will not be seen during a videoconference while areas in front of the designated regions remain viewable.

Securing image data from unintended disclosure at a videoconferencing endpoint

Multiple cameras in a conference room, each pointed in a different direction and including a microphone array to perform sound source localization (SSL). The SSL is used in combination with the video image to identify the speaker from among multiple individuals that appear in the video image. Neural network or machine learning processing is performed on the identified speaker to determine the quality of the front or facial view of the speaker. The best view of the speaker's face from the various cameras is selected to be provided to the far end. If no view is satisfactory, a default view is selected and that is provided to the far end. The use of the SSL allows selection of the proper individual from a group of individuals in the conference room, so that only the speaker's head is analyzed for the best facial view and then framed for transmission.

Intelligent multi-camera switching with machine learning

A teleconferencing system, comprising: a camera, wherein the camera is configured to capture an image data stream comprising one or more image data frames in accordance with one or more image-capture parameters; and a processor coupled to the camera, wherein the processor is configured to: receive the image data stream from the camera; determine a region of interest within an image data frame of the image data stream; identify a sub-portion of the image data frame corresponding to the region of interest; evaluate a quality of image data corresponding to the sub-portion; determine that the quality of the image data corresponding to the sub-portion is below one or more predetermined quality thresholds; update one or more of the image-capture parameters of the camera, responsive to determining that the quality of the image data corresponding to the sub-portion is below the one or more predetermined quality thresholds.
