More Information
Summary:A method of characterizing alignment between two images includes receiving a first data set representative of a reference image, receiving a second data set representative of a target image, processing the first and second data sets that includes calculating an autocorrelation of the first data set to obtain a third data set that is substantially absent information representative of a relative shift between the reference image and the target image, and processing the third data set that includes calculating a Radon transform of the autocorrelation of the first data set to obtain a fourth data set that includes information representative of a relative rotational difference between the reference image and the target image.
