摘要:
Methods are provided for estimating motion between images associated with a common region of interest, the method comprising:
providing frames including a reference frame and a target frame;
determining a global motion vector based on a comparison of the reference and target frames;
for a plurality of local blocks, determining local motion vectors between the reference and target frames based on the global motion vector to form globally adjusted local motion vectors;
considering the globally adjusted local motion vectors as motion estimator.
A corresponding system is also disclosed.
