Image sequence restoration for removing space-variant motion blur

An image restoration algorithm for removing motion blur, which occurs in an image sequence or moving pictures, is proposed. More specifically, the proposed iterative restoration algorithm adaptively reduces nonuniform motion blur by using motion vector information from consecutive image fields. Motion vectors are estimated based on the well known block matching algorithm, and the corresponding blur model is embodied into the point spread function, which is used to implement the iterative image restoration algorithm. A blur model modification method is also proposed to reduce artifacts on the boundary area between objects with different blur patterns.
