SYSTEM AND METHOD FOR REGISTERING IMAGES

摘要

A method and system for registration system of a first and a corresponding second image are described. The method comprises the steps of converting the spatial image data into frequency domain data using, for example, a fast Fourier transform (FFT); determining a correlation map between the two images by calculating the inverse transform of the complex conjugate product of the frequency domain data of the first and the second image; and identifying a translation between the two images on the basis of the correlation map.
