Abstract
A system and method involve receiving a sequence of images of an object with at least two consecutive images of the sequence being spatially shifted relative to each other. Each image is transformed into a Fourier domain using a Fourier transform to generate a corresponding plurality of Fourier transformed images. An amplitude filtered pattern is calculated in the Fourier domain based on amplitude components of the plurality of Fourier transformed images. Spatial shifts for pairs of consecutive images in the sequence of images are determined using the amplitude filtered pattern. Images in the sequence of images are aligned based on the determined spatial shifts and the aligned images are summed to form an image-shift-corrected summed image.
