Abstract A method for twoimage registration with rigid transformation is proposed. It directly constructs an evaluation function of rotations, which comes from the quadratic sum of the one dimensional phase correlation between the Randon transforms in the two aligned images. The coordinate of the maximum value of this function yields the estimate for rotation angle. Experimental results show that the proposed method outperforms phaseonly bispectrum based method, and it can estimate both arbitrary rotations and medium translations robustly and accurately.
