Research Abstract

We show that variational method for image registration provides a method for the computation of average of medical organ images. By selection criteria for the variational computation, the method yields the sharp average image. The method tracks the temporal motion of organs such as beating heart. This tracking method extracts evolution of cancers. The method is also usable to the up-conversion of video sequence observed in long-distance remote exploration.
