Abstract: In the useof Fourier transform phase correlation image alignment principles of right,based on a improved traditional Fourier transform image registration algorithm canbe improved by using the pyramid from coarse to fine hierarchical registration strategy,and high robustness the image with accuracy can be effectively improved.Experimental results show that the algorithm has quasi-precision,high speed,and highly robust.

Key words: image registration, Fourier transform, phase correlation, sub-pixel
