Abstract
A method of ultra-low rate video encoding, including capturing a frame within a video stream, capturing a global position of the frame, capturing a heading of the frame, linking the global position and the heading to the frame, determining a foreground of the frame based on the global position of the frame and the heading of the frame, determining an at least one region of interest within the foreground, analyzing the at least one region of interest, removing a background from the frame based on the global position and the heading, wherein the background is complementary to the foreground and encoding the foreground, the global position, the heading and the at least one region of interest.
