Abstract:
 We have applied techniques from differential motion
 estimation to the problem of automatic elastic registration of medical
 images. This method models the mapping between images as a locally
 affine but globally smooth warp. The mapping also explicitly accounts
 for variations in image intensities. This approach is simple and
 highly effective across a broad range of medical images. We show the
 efficacy of this approach on several synthetic and clinical images.
