摘要： A video conference call system is provided with a camera to generate an input frame image of a conference room, where the video conference call system detects a human head for each meeting participant captured in the input frame image by applying a machine learning human head detector model to said input image frame, generates a head bounding box which surrounds each detected human head and identifies a corresponding meeting participant, extracts a pixel width measure and pixel height measure from each head bounding box, and applies the extracted pixel width measure and pixel height measure to one or more reverse lookup tables to extract meeting room coordinates for each meeting participant identified by a corresponding head bounding box.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Providing a facilities supervisor notice after a conference room or other common area has been used and is in a messy condition. An image of the conference room obtained after use is evaluated to determine if the conference room is neat. A neatness score is obtained for the conference room. If the score indicates a neatness value above a settable level, the conference room is considered clean and ready for use. If the neatness score indicates a neatness value less than the settable level, the conference room is not ready for use, and a notice is provided to the facilities supervisor to allow a cleaning person to be dispatched. The need to perform the cleanliness or neatness review is triggered by referencing scheduled meetings in a calendaring system, by monitoring the conference room for the presence of individuals having an unscheduled meeting and periodically or randomly.

摘要： A head-worn audio device is provided with a circuit for voice signal enhancement. The circuit comprises at least a plurality of microphones, arranged at predefined positions, where each microphone provides a microphone signal. The circuit further comprises a directivity pre-processor and a blind source separation processor. The directivity pre-processor is connected with the plurality of microphones to receive the microphone signals and being configured to provide at least a voice signal and a noise signal. Directivity pre-processing increases the mutual independence of the signals provided to the blind source separation processor and thus improves processing by blind source separation. The blind source separation processor receives at least the voice signal and the noise signal, and is configured to conduct blind source separation on at least the voice signal and the noise signal to provide at least an enhanced voice signal with reduced noise components.

摘要： Embodiments of the present disclosure include an apparatus with a camera. A shutter is positioned horizontally in front of the lens of the camera. The shutter is configured to move in front of a lens of the camera and is further configured to move orthogonally to the horizontal axis so as to at least partially obscure the lens of first camera in a closed shutter position. The apparatus further includes a motor positioned horizontally behind the front of the lens of the camera. The motor is configured to move the shutter orthogonally to the horizontal axis between the closed shutter position and an open shutter position.
