摘要： Eye gaze reduction may be provided. First, a location of a near-end camera relative to a near-end screen may be determined. Next, based upon the determined location of the near-end camera, a location may be determined for a video window on the near-end screen. The determined location for the video window may be configured to reduce an eye gaze error in a near-end image transmitted to a far-end device from the near-end camera. Then video data from a far-end camera corresponding to the far-end device may be received and rendered in the video window at the determined location for the video window on the near-end screen.

摘要： A dynamically adjustable framed view of occupants in a room is captured through an automatic framing system. The system employs a camera system, including a pan/tilt/zoom (PTZ) camera and one or more depth cameras, to automatically locate occupants in a room and adjust the PTZ camera's pan, tilt, and zoom settings to focus in on the occupants and center them in the main video frame. The depth cameras may distinguish between occupants and inanimate objects and adaptively determine the location of the occupants in the room. The PTZ camera may be calibrated with the depth cameras in order to use the location information determined by the depth cameras to automatically center the occupants in the main video frame for a framed view. Additionally, the system may track position changes in the room and may dynamically adjust and update the framed view when changes occur.
摘要翻译：通过自动框架系统捕获房间中乘客的动态调整框架视图。该系统采用摄像系统，包括云台/变焦（PTZ）摄像机和一个或多个深度摄像机，以自动定位房间中的乘客，并调整PTZ摄像机的摇摄，倾斜和缩放设置，以聚焦于乘员并将它们放在主视频帧中。深度相机可以区分乘客和无生命物体，并自适应地确定乘客在房间中的位置。可以使用深度摄像机校准PTZ摄像机，以便使用由深度摄像机确定的位置信息来自动将居住者居住在主视频帧中以进行框架视图。此外，系统可以跟踪房间中的位置变化，并且可以在发生变化时动态地调整和更新框架视图。

摘要： A region of interest may be determined using any or all of sound source location, multi-person detection, and active speaker detection. An weighted mean may be determined using the region of interest and a set of backlight weight regions, or, only the set of backlight weight regions if a region of interest could not be found. The image mean is compared to a target value to determine if the image mean is greater than or less than the target value within a predetermined threshold. If the image mean is greater than the predetermined target value and predetermined threshold value, the gain and exposure are decreased. If the image mean is lesser than the predetermined target value minus the predetermined threshold value, the gain and exposure are decreased.

摘要： Techniques are described for embedding a panoramic image in standard resolution. A panoramic image is received from a panoramic camera and a location of a speaker is determined, either automatically or manually. A portion of the panoramic image is cropped to isolate the speaker and the cropped portion of the image is enlarged to standard video resolution. The panoramic image is combined with the cropped portion and transmitted via a standard video streaming format. In at least one implementation, the panoramic image is normalized so that face sizes of persons in the image appear approximately equal regardless of the distance each person is situated relative to the camera.
摘要翻译：描述了以标准分辨率嵌入全景图像的技术。从全景相机接收全景图像，并自动或手动确定扬声器的位置。全景图像的一部分被裁剪以隔离扬声器，并且图像的裁剪部分被放大到标准视频分辨率。全景图像与裁剪的部分组合并通过标准视频流格式传输。在至少一个实施方案中，全景图像被归一化，使得图像中的人的面部尺寸看起来大致相等，而不管每个人相对于照相机的距离。
