Abstract

In V2V or other networks in which multiple video feeds are available to a participant, a participant can select a particular video feed for display. The participant has the option of selecting or locking onto a particular camera so that the display continues to show scenes captured by that camera without regard to what appears in those scenes. As an alternative, the participant may select or lock onto a particular scene. If a scene is selected, the current video feed is analyzed to identify key features. The video feed is monitored. If the key features disappear from the video feed, video feeds available from other cameras are analyzed for the presence of the key features. A new video feed (i.e., camera) is selected from the set of video feeds currently generating images including the key features.
