Abstract:
A method and system for filtering an image frame of a video sequence from spurious motion, comprising the steps of dividing the image frame and a preceding image frame of the video sequence into blocks of pixels; determining motion vectors for the blocks of the image frame; determining inter-frame transformation parameters for the image frame based on the determined motion vectors; and generating a filtered image frame based on the determined inter-frame transformation parameters; wherein the image frame is dived into overlapping blocks.
