Study on an Image Registration Algorithm Based on Fourier-Mellin

This paper proposes an image registration algorithm based on Fourier-Mellin. The images using some techniques such as windowing and filtering, which removes spurious high-frequencies in spectral leakage created by the image boundary, greatly reduces the ratationally dependent aliasing, increases the signal- to-noise ratio of the images and improves the efficiency and accuracy of the phase correlation algorithm. Experimental results demonstrate the efficiency of the proposed algorithm.
