摘要： A method may include identifying, in a frame of a video feed, a region of interest (ROI) and a background, encoding the background using a first quantization parameter to obtain an encoded low-quality background, encoding the ROI using a second quantization parameter to obtain an encoded high-quality ROI, and encoding location information of the ROI to obtain encoded location information. The method may further include combining the encoded low-quality background, the encoded high-quality ROI, and the encoded location information to obtain a combined package. The method may further include transmitting the combined package to a remote endpoint.

摘要： A videoconferencing device at an endpoint determines whether a person is a real person standing in front of a display device or if the person is instead an image rendered by a display device. In the first instance the real person will be included in a video feed for transmission to a remote endpoint. In the second instance, images of the display device on which the person is rendered will not be included in the video feed.

摘要： A method (1000) for operating cameras (202) in a cascaded network (100), comprising: capturing a first view (1200) with a first lens (326) having a first focal point (328) and a first centroid (352), the first view (1200) depicting a subject (1106); capturing a second view (1202) with a second lens (326) having a second focal point (328) and a second centroid (352); detecting a first location of the subject (1106), relative the first lens (326), wherein detecting the first location of the subject (1106), relative the first lens (326), is based on audio captured by a plurality of microphones (204); estimating a second location of the subject (1106), relative the second lens (326), based on the first location of the subject (1106) relative the first lens (326); selecting a portion (1206) of the second view (1202) as depicting the subject (1106) based on the estimate of the second location of the subject (1106) relative the second lens (326).

摘要： A method for tracking movement of a presenter during a videoconference comprises tracking the location of subject of interest; quickly detecting error conditions—such as can occur when a subject of interest moves too quickly or when a subject of interest walks past another person—and quickly reinitiating the tracking sequence to help ensure a positive videoconferencing experience.

摘要： A teleconferencing system (100) comprises: a first camera (202) including a first lens (326) having a first focal point (328) and a first centroid (352), and configured to capture a first view (900) corresponding to a subject (702); a second lens (326) having a second focal point (328) and a second centroid (352), and configured to capture a second view (902) corresponding to the subject (702); and a processor (206) coupled to the first camera device (202) and the second camera device (202). The processor (206) is configured to: estimate a first orientation (351) of the subject (702) relative the first lens (326) and a second orientation (351) of the subject relative the second lens (326); and determine that the first orientation (351) is more closely aligned with a first line (307) from the first centroid (352) to the first focal point (328) than is the second orientation (351) aligned with a second line (307) from the second centroid (352) to the second focal point (328).

摘要： A method of tracking a presenter during a videoconference, comprising: detecting, in a data stream, data indicating a presence of one or more persons at a videoconferencing endpoint, the data stream comprising a plurality of frames; detecting tracker initiation data (e.g., that a person is actively talking, or that a person has raised their hand, or both) in the data stream; determining a subject of interest responsive to the tracker initiation data, and tracking the subject of interest as they move while making a presentation.
