Abstract: A temporal object segmentation system determines a location of an object depicted in a video. In some cases, the temporal object segmentation system determines the object's location in a particular frame of the video based on information indicating a previous location of the object in a previous video frame. For example, an encoder neural network in the temporal object segmentation system extracts features describing image attributes of a video frame. A convolutional long-short term memory neural network determines the location of the object in the frame, based on the extracted image attributes and information indicating a previous location in a previous frame. A decoder neural network generates an image mask indicating the object's location in the frame. In some cases, a video editing system receives multiple generated masks for a video, and modifies one or more video frames based on the locations indicated by the masks.

Abstract: Systems and methods for transitioning a call between two devices are disclosed herein. An origin device for the call is determined based on a first position of an ultra-wideband (UWB) device. A destination device for the call is then determined based on a second position of the UWB device. The UWB device sends transition commands to both the origin device and the destination device, each transition command including an identifier of the other device. Using the identifier of the origin device, the destination device connects to the call the origin device is currently participating in. When the origin device detects that the destination device has connected to the call, the origin device disconnects from the call.
