1. A method for image frame registration, comprising the steps of:

  • storing first and second image frames of pixel values;

    transforming said first and second image frames into first and second frequency domain representations respectively using a two-dimensional Fast Fourier transformation;

    processing said first and second frequency domain representations to determine a rotation parameter and a scaling parameter needed for said first image frame to be in registration with said second image frame;

    rotating said first image frame in accordance with said rotation parameter; and

    scaling said first image frame in accordance with said scaling parameter.
