Abstract: Systems and methods for multi-attendee video conferencing are described. A system can convert from huddle video conference mode to spatial video conference mode. In particular, by assigning user roles, specific users can have greater control of the video conference as compared to other users. For instance, moderators may have a greater level of control of the video conferencing system. Thus, in example implementations of the present disclosure, specific users can affect transition between two or more video conferencing modes, such as between a huddle video conference mode and a spatial video conference mode.

Abstract: A computing system and method that can be used for safe and privacy preserving video representations of participants in a videoconference. In particular, the present disclosure provides a general pipeline for generating reconstructions of videoconference participants based on semantic statuses and/or activity statuses of the participants. The systems and methods of the present disclosure allow for videoconferences that convey necessary or meaningful information of participants through presentation of generalized representations of participants while filtering unnecessary or unwanted information from the representations by leveraging machine-learning models.

Abstract: An image capture device, such as a camera, has multiple modes including a light field image capture mode, a conventional 2D image capture mode, and at least one intermediate image capture mode. By changing position and/or properties of the microlens array (MLA) in front of the image sensor, changes in 2D spatial resolution and angular resolution can be attained. In at least one embodiment, such changes can be performed in a continuous manner, allowing a continuum of intermediate modes to be attained.
