Abstract
A method of stabilizing a video in real time using a single pass including receiving consecutive video frames, where the consecutive video frames include a current video frame and previous video frames, storing the consecutive video frames in a buffer, estimating a global motion for the current video frame by describing a camera's relative motion between the current video frame and one of the previous video frames adjacent to the current video frame, estimating a long-term camera motion for the current video frame by determining a geometric mean of an accumulation of the estimate of the global motion for the current video frame and an estimate of global motion for each of the previous video frames, and displaying the current video frame on a display of an electronic device, the current video frame stabilized based on the estimate of the long-term camera motion.
