Abstract: A conferencing endpoint selects a background for a conferencing system. The conferencing endpoint captures an initial series of images of a foreground object in front of a background image, and segments at least one frame of the initial series of images into the foreground object and the background image according to a first segmentation technique. The conferencing endpoint generates one or more test backgrounds and evaluates the test backgrounds according to a second segmentation technique. The conferencing endpoint selects a final background from the test backgrounds for segmenting a subsequent series of images according to the second segmentation technique.

Abstract: Techniques for creating an optimal and secure data plane based on network constraints. The techniques may include establishing an initial networking connection for a data flow between a client device and a resource such that data plane traffic of the data flow is routed through a relay node disposed between the client device and the resource. In some examples, the techniques may include determining, using a Session Traversal Utilities for Network Address Translators (STUN) server, an alternate networking connection for the data flow that bypasses the relay node. Based at least in part on a determination that the alternate networking connection is a more optimal path for the data plane traffic than the initial networking connection, the techniques may include causing the data plane traffic of the data flow to be routed over the alternate networking connection.

Abstract: In one example embodiment, audio characteristics of audio signals are adjusted by a first machine learning model to reduce effects of a facial covering and produce adjusted audio signals. The audio signals correspond to resulting voice signals produced from the facial covering affecting original voice signals. Speech characteristics are predicted for the adjusted audio signals by a second machine learning model. Transformed audio signals corresponding to the original voice signals are produced based on the adjusted audio signals and predicted speech characteristics.

Abstract: An apparatus configured to perform resilient data plane processing using multiple network streams may comprise a memory and a processor communicatively coupled to one another. The processor may be configured to establish a connection with the data aggregator, and request access to one or more resources from a data aggregator. Further, the processor may be configured to receive a first data stream and a second data stream from the data aggregator, combine a version of the first data stream and a version of the second data stream into a local data stream, and present the local data stream.

Abstract: Techniques for syncing authentication and/or authorization tokens, cookies, and related metadata across different browser instances to enable disparate applications to share a single authentication/authorization ceremony. The techniques may include receiving a policy indicating multiple enterprise-managed applications that are capable of sharing tokens or cookies for user authentication. The techniques may also include receiving a token or a cookie indicating that a user is authenticated to access a first application of the multiple enterprise-managed applications. Based at least in part on the policy, the token or the cookie may be provided to a browser such that a second application of the multiple enterprise-managed applications refrains from causing the user to authenticate for access to the second application.
