Reliability metric of motion vectors and its application to motion estimation

This paper proposes a reliability metric for motion vectors, and applies it to the block matching method using hierarchical images to reduce estimation errors. First, the proposed reliability metric for motion vectors is derived and its properties are discussed. In order to evaluate the usefulness of the proposed reliability metric, a calculation example for an actual image is shown. Then, the derived reliability metric is applied to the block matching method using hierarchical images as a weighting function. Finally, several experimental results by the proposed estimation method are shown for a verification of the proposed method.
