Abstract: Described are multiple cameras in a conference room, each pointed in a different direction. A primary camera includes a microphone array to perform sound source localization (SSL). The SSL is used in combination with a video image to identify the speaker from among multiple individuals that appear in the video image. Pose information of the speaker is developed. Pose information of each individual identified in each other camera is developed. The speaker pose information is compared to the pose information of the individuals from the other cameras. The best match for each other camera is selected as the speaker in that camera. The speaker views of each camera are compared to determine the speaker view with the most frontal view of the speaker. That camera is selected to provide the video for provision to the far end.

Abstract: A trajectory prediction apparatus is configured to execute the following operations. A reference path line is selected from multiple path lines of a scene based on multiple first trajectory coordinates of an object, wherein the first trajectory coordinates and the path lines correspond to a first coordinate system. The first trajectory coordinates of the first coordinate system are transformed into multiple second trajectory coordinates corresponding to a second coordinate system, wherein the second trajectory coordinates indicate relationships of the object corresponding to the reference path line. A predicted trajectory of the object is generated based on the second trajectory coordinates by using a prediction model.
