Abstract
A method for the correction of images that are subject to spatial warping is presented. The correction method applies to two-dimensional images and employs the construction of a complex-valued interpolating polynomial. The construction is based on defining a set of points in an image whose desired location is known. The coefficients of the polynomial are shown to satisfy a recursion relation that simplifies implementation and improves evaluation efficiency. Results are presented for a two-dimensional slice from a magnetic resonance image.
