Besides the feature-based method, we have developed two methods based on the intensity of all pixels (or voxels) in the datasets. One starts by transforming the datasets from the Cartesian space into the Fourier space. Then, the translation, rotation and scaling are found and applied to one of the datasets. To cope with local deformations, a second method changes one of the datasets locally in order to maximize a similarity measure.
