Abstract: The disclosed computer-implemented method may include systems for incorporating a user's avatar into a real-time communication session. For example, the described systems establish a real-time communication session between two or more social networking system users. The described systems further generate a landmark map representing positioning of one of the real-time communication session participants, and transmit the landmark map with the participant's avatar to one or more recipients. On the recipient-side, the described systems render the transmitted avatar according to the landmark map. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A system can include one or more processors configured to execute a first object tracker to detect one or more objects in images received via a sensor of a device, monitor one or more metrics of the first object tracker, determine that the one or more metrics do not meet a criteria corresponding to a profile of the device, and use, responsive to the determination, a second object tracker instead of the first object tracker.
