    To eliminate the image jittering from the vibration caused by the translation motion of a camera, a method of digital image stabilization based on morphological edge pattern matching is proposed. In this method, morphological edge matching is used to estimate the local movement vectors based on the 1 bit edge maximal correlation. Since correlation calculation is logical operator instead of pixel-wise gray arithmetic operators, the complexity of proposed method is greatly reduced. Moreover, in order to remove the undesired local motion vectors caused by several undesired conditions, the local motion vectors are analyzed to judge whether it is desired or not and to eliminate the effects of locate motion target,low contrast and texture pattern regions on the estimation of globe motion vectors.Finally, the reliable globe movement vector is obtained by weight median. Experiments show that this method is fast and efficient for image stabilization, and can be applied in the video vibrations without large rotations.
