Abstract
In recent years, fractional Fourier transform (FRFT) which contains both spatial and frequency information has been a hot topic. Image registration (IR), as an important preprocessing procedure, is very promising to be implemented on FRFT domain. A novel method based on the properties of FRFT and conventional phase correlation technique is proposed in this paper. This method not only can get more accurate results than previous FRFT-based methods, but also avoids the iterative operation, which greatly reduces the computation complexity. Simulation results prove the proposed superiority than existing methods based on FRFT.
