1. Method for multi-view image registration comprising the steps of:

  • a) receiving a plurality of images;

    b) establishing an ideal coordinate system;

    c) processing the received images to register the images to the ideal coordinate system using none of the plurality of images as a reference image, including the steps of;

    c1) selecting at least two images from the plurality of images;

    c2) computing a plurality of motion parameters to warp the at least two images to the ideal coordinate system as at least two warped images respectively; and

    c3) minimizing an objective function that characterizes differences between the at least two warped images in the ideal coordinate system by iteratively deriving the motion parameters in a coarse-to-fine manner over a set of image pyramids to produce the further set of parameters which define the parametric transformation.
