A novel method for electronic image stabilization based on phase-correlation is proposed.Firstly,a central patch is cropped on the reference image,then the same size patch is found on the stabilized image,which makes the inverse Fourier transform for the cross power spectrum of the two patches in log-polar representation be a 2D impulse.The coordinate of the selected patch centre on the stabilized image corresponds to the translated parameter exactly.And the impulse location can determine the scaled and rotated factors,so as to obtain translation,rotation and scale parameters.Experimental results show that this method is efficient,and satisfy the general demand.
