| Research Abstract |
While maximum likelihood has been used for high accuracy geometric estimation from image data, such as fitting lines and ellipses and computing the relationships between corresponding points over multiple images, we have derived a higher accuracy method, called “hyper-renormalization” and applied it to various practical problems. At the same time, we have extend the “hyper accurate correction” for correcting the maximum likelihood solution and confirmed that the same degree of accuracy can be reached. We have also introduced a new formulation of the extended FNS method and applied it to the analysis of the GPS land deformation data of the Great East Japan Earthquake.
