发明名称 METHOD AND SYSTEM FOR DIGITAL IMAGE STABILIZATION
摘要 The present invention relates to a method and system for a digital image stabilization intended to remove unwanted camera movement or jitter, both trans lational and rotational jitter. The system comprises the following means : 1) a motion estimation stage (10) of the global motion of the camera: block motion vectors are calculated for specific parts of the image and global motion parameters representing the camera motion are then derived. 2) a motion/jitter filtering stage (11): the translation vector and the rotation angle are filtered separately, a boundary check being then performed for verifying if the correction thus done is not above an allowed threshold. 3) a jitter compensation stage (12): the raw sequence is compensated according to the extracted jitter and the result is a stabilized sequence.
