Abstract
A method for digital video image stabilization, the method including: estimating, from at least one portion of a frame, global frame displacement between an initial reference digital video frame and a current frame in a video sequence of frames; verifying, for the entire frame, the validity of the estimated frame displacement; and compensating for the estimated frame displacement by aligning at least one frame in the sequence with respect to the initial reference frame; wherein the step of aligning includes producing a corrected motion vector for the frame to be aligned and displacing the frame within the video frames sequence in accordance with the corrected motion vector.
