** Previous:** Multiresolution

- The first image shows how small, pixel windows from each image at each scale are transformed using the Fast Fourier Transform algorithm. This speeds up the computation of the cross-correlation algorithm, using the `shift theorem' of the FT.
- The next image is the final estimate of the geometry correction field, shown as a colour image, where the hue indicates direction and intensity the length of the warp vector at each pixel.
- Next are results from a pair of Candida gels, showing how it works. For this pair of gels, the error after warping was only of that before warping. The sequence is an interleaving of the intermediate results at the various scales, from top to bottom of the pyramid: the `target' image is followed by the warped prototype.
- The second image set is four gels from the Candida set all warped to the same geometry.
- The final set are some breast cancer tissue samples, which show significantly more variation in pattern than the Candida set.
