Abstract: The number of persons in a still image acquired during a videoconference may change over time due to movement or persons entering or exiting a conference room. Minimizing the number of person identifiers that are tracked is beneficial for framing purposes. Typically, a stream of frames is sent to a far side, such as another endpoint device, for viewing. If the number of persons identified keeps changing, the composition of the stream of frames will be constantly changing as well. By using person identification and the use of timers, movement by the same person or a temporary change in a number or set of persons may be detected without making changes to the number of identifiers and persons being framed. It is only when a change has persisted past a period of time that changes are made to the frames, thereby improving the overall viewing experience.

Abstract: A method for hybrid noise suppression includes receiving a processed audio signal from an audio device. The processed audio signal results from a partial audio processing performed on a noisy audio input signal. The method further includes predicting a noise suppression parameter using a neural network model operating on the processed audio signal and generating a noise-suppressed audio signal from the processed audio signal, using the noise suppression parameter. The method further includes generating a noise-suppressed audio output signal from the noise-suppressed audio signal using an additional audio processing and outputting the noise-suppressed audio output signal.

Abstract: Determining the angle of sound relative to the centerline of a microphone array. The angle of the centerline of a camera field-of-view (FoV) and the angle of the camera FoV is determined. Knowing the angle from the centerline of the microphone array of the particular sound and then the angle of the centerline of the camera FoV and angles of the camera FoV allows a determination if the sound is inside the FoV of the camera. If so, the microphones are unmuted. If not, the microphones are muted. As the camera zooms or pans, the changes in camera FoV and centerline angle are computed and used with the sound angle, so that the muting and unmuting occurs automatically as the camera zoom and pan angle change.

Abstract: A method including generating, by applying a three-dimensional pose estimation model to an original image generated by a camera, estimated three-dimensional poses for people in the original image. The estimated three-dimensional poses include distances from the camera. The method further includes determining, using the distances, a far people subset of the people. Each person of the far people subset corresponds to a distance from the camera exceeding a threshold distance. The method further includes, deriving, for the far people subset, regions of interest, upscaling a region of interest for a person of the far people subset to generate an upscaled region of interest, and generating, from the original image and the upscaled region of interest, an enhanced image.

Abstract: A speaker system includes a speaker, a processor, and an active noise cancellation (ANC) circuit communicatively coupled with the processor. The ANC is configured to apply ANC on audio signals from outside the speaker system to generate a modified audio signal stream through the speaker.

Abstract: Scene changes should be done pleasingly and without user input or control. Based on the number of speakers and changes in speakers, either to a different individual or movement by the same speaker, based on the locations of the speakers, and based on the overlap of the current and intended scenes, a decision is made whether to perform a smooth transition or do a cut. It has been determined that the decision on cut versus smooth transition is preferably based on the location of the center of the intended new scene versus the boundaries of the current scene, a cut used if the center is outside the boundaries and a smooth transition if inside. If a smooth transition, an easing function, such as ease in ease out, is performed to change the scene. A preferred value for the smooth transition is to perform the transition over 80 frames.
