3. in video, each frame carries out relevant Feature Points Matching to benchmark image;
4. the distance obtained between a unique point of benchmark image and match unique point of the i-th two field picture is
, suppose that the frame per second of video is
, then the speed of unique point motion is
, reset a rate-valve value T, if
time, then remove this unique point, otherwise retain this unique point; Because the speed of shaking in video is generally smaller, and the velocity ratio of moving target is larger.
5. to the image motion compensation of being correlated with of shake: by the unique point coordinate of the first frame in the video that obtains
with the unique point coordinate that jth frame matches
, jth frame picture shift amount can be obtained
, then
,
with
meet:
Therefore, in order to compensate the randomized jitter of video, by the jth frame picture (shake frame) in video
pass through translation
realize shake frame
motion compensation, thus obtain stable after image;
6. preserve motion compensated jth frame picture, also correlative compensation is carried out to other two field pictures, until video terminates.
