摘要： This disclosure describes a method and system to perform object detection and 6D pose estimation. The system comprises a database of 3D models, a CNN-based object detector, multiview pose verification, and a hard example generator for CNN training.
The accuracy of that detection and estimation can be iteratively improved by retraining the CNN with increasingly hard ground truth examples. The additional images are detected and annotated by an automatic process of pose estimation and verification.

摘要： An apparatus is provided in one example and includes a camera configured to receive image data associated with an end user involved in a video session. The apparatus also includes a display and an optics element configured to interface with the camera. The optics element reflects the image data associated with the end user positioned in front of the display. A retracting mechanism is also provided and is configured to retract the optics element in a direction such that the camera moves to an inactive state and the optics element is removed from a view of the display from the perspective of the end user. An effective optical distance from the camera to the end user is increased by manipulating a position of the optics element. In more detailed embodiments, the camera can be configured above the display such that its lens points downward toward the optics element.

摘要： A method, an apparatus, and a storage medium with executable code to execute a method including accepting camera views of at least some participants of a teleconference, each view from a corresponding video camera, with the camera views together including at least one view of each participant. The method includes accepting audio from a plurality of microphones, and processing the audio from the plurality of microphones to generate audio data and direction information indicative of the direction of sound received at the microphones. The method further includes generating one or more candidate people views, with each people view being of an area enclosing a head and shoulders view of at least one participant. The method also includes making a selection, according to the direction information, of which at least one of the candidate people views are to be transmitted to one or more remote endpoints.

摘要： An apparatus, software encoded in tangible media, and a method at an encoder. The method includes sending compressed video data including a reference frame message to create a long term reference frame to a plurality of decoders at one or more destination points, receiving feedback from the decoders indicative of whether or not the decoders successfully received the reference frame message, and in the case that the received feedback is such that at least one of the decoders did not successfully receive the reference frame message or does not have the indicated recent frame, repeating sending a reference frame message to create the long term reference frame. Using the method can replaces I-frame error recovery with long term reference frames, even in the case where the reference frame management messages are lost to at least one decoder.

摘要： A system and method for creating a virtual round table videoconference is described. An embodiment of the system comprises a plurality of displays arranged in an arc configuration with a table to create a virtual round table. Cameras are arranged around the plurality of displays such that when a participant looks at a display with an image of a remote participant, the camera associated with the display captures an image of the participant's gaze, making eye contact with the camera. The image is displayed at the remote participant's endpoint creating the effect of eye contact between the participants. In another embodiment, audio speakers are arranged to provide directional sound such that the video source for a display and the audio source for the associated speaker are from the same endpoint.
