Abstract: A method enhances brightness in video frames of a video during streams. The method includes determining, by a processor, that a first video frame has low light. The method further includes applying, by the processor, a linear correction to provide a first brightness enhancement in the first video frame that modifies a first brightness of a predetermined darkest percentage of pixels to be less than a darkness threshold value or a second brightness of a predetermined lightest percentage of the pixels to be greater than a lightness threshold value. The method further includes averaging, by the processor, the first brightness enhancement of the first video frame with a set of brightness enhancements corresponding to previous video frames to generate a modified video.

Abstract: A method for context-dependent in-call video codec switching includes receiving an indication that a far-side endpoint includes a capability to switch from an initial video codec to a secondary video codec during a call. During a call with the far-side endpoint, the method includes determining that a performance of an encoder satisfies a codec switching threshold. The codec switching threshold indicates that the performance of the encoder justifies switching from the initial video codec mid-stream of the call. During a call with the far-side endpoint, the method also includes switching from the initial video codec initially negotiated to govern the call to the secondary video codec.

Abstract: Systems and methods of the present disclosure are directed to automatic control of mute controllers for participants in videoconferences. For example, a method for automatically controlling a mute control associated with a participant during a videoconference includes obtaining communication data associated with the participant participating in the videoconference. The communication data includes audio signals associated with the participant and/or visual signals associated with the participant. The method includes processing the communication data by a gate control model to generate an output. The output is indicative of an intent of the participant to communicate with other participants of the videoconference. The method includes generating a noise gate status based at least in part on the output associated with the gate control model. The method includes automatically controlling the mute control of the participant based at least in part on the noise gate status.
