Abstract
A system and method are described for an image registration system and method including a registration engine that receives complex image data for corresponding images. The registration engine generates a correlation map between the complex image pair for relative translation by calculating an inverse of the complex conjugate product of the frequency data of the first image and the frequency domain data of the second, corresponding, image. The frequency domain data may be obtained using Fast Fourier transform-based techniques.
