Phase-Based Multidimensional Volume Registration

Abstract-- We present a method for accurate image registration and motion compensation in multidimensional signals, such as 2D X-ray images and 3D CT/MRI volumes. The method is based on phase from quadrature filters, which makes it robust to noise and temporal intensity variations. The method is equally applicable to signals of two, three or higher number of dimensions. We use parametric models, e.g. affine models, finite elements or local affine models with global regularization. Experimental results show high accuracy for 2D and 3D motion compensation.
