The researchers are studying motion estimation for applications                 in image processing such as motion compensation in image                        encoding.  The researchers are also using motion estimation for                 improving image sequence restoration and in the problem of                      interpolating between two adjacent image frames.  They have                     developed a new approach to motion estimation which is model-                   based and uses a multi-grid for computational efficiency.  The                  method involves a careful solution of two linear velocity                       equations resulting from a least-squares analysis.  Also for                    noise immunity, they approximate the relevant partial derivatives               by low order polynomial interpolation rather than first order                   differences.  The new technique includes an accurate detection of               regions where the motion estimates are not good enough to be                    useful for the above tasks.
