Method and apparatus for video stabilization

Abstract

A method and an apparatus for video stabilization is disclosed for detecting and eliminating unwanted camera motion from a sequence of video images. Motion vectors are first generated based on sample points using a block matching technique, from which a number of possible camera motions are estimated. Among the estimated camera motions, unwanted or undesirable camera motions are then detected and parameterized. A frame remapping process is then applied to relocate the pixels in the current frame, which acts in opposition to the dislocation of pixels due to unwanted camera motions in order to achieve video stabilization.
