Abstract

An image in a base domain (e.g., spatial) is restored from only one component (e.g. magnitude) of a transform-domain (e.g., Fourier) image by combining this component with a complementary component (e.g., phase) of a transformed previous iteration. Every iteration is converted to the base domain, and predefined known marker and padding data is reapplied to the iteration during every iteration, for convergence purposes (120, 120`, 121). The restored image can be scaled and trimmed, and the marker position interpolated (151). The original image to be restored is modified to contain the known marker and known padding at known locations. These may be inserted in the base domain or in the transform domain.
