Abstract
Method for computer-aided motion estimation in a plurality of temporally successive digital images. The method includes first partial motion estimating in a second digital image relative to a first digital image temporally preceding the second digital image; constructing a reference image structure from the first digital image and the second digital image based on the first partial motion estimation, the reference image structure containing at least features from the first digital image and/or the second digital image; second partial motion estimating in a third digital image, which temporally succeeds the second digital image, relative to the second digital image; third partial motion estimating with a comparison of features of the third digital image and of the features contained in the reference image structure; and determining motion in the third digital image relative to the first digital image based on the third partial motion estimation, the second partial motion estimation and the first partial motion estimation.
