Abstract :
This method is an extension of the phase correlation method for image registration to multidimensional data sets. Through use of a high-order singular value decomposition, phase correlation can be used to identify translational displacements independently along each dimension with subpixel resolution. The validity of this approach is demonstrated using multiple 3D MRI data sets.
