interpolation independently along each dimension, and specify interpolants
that you define.
Image Registration
Version 3.0 adds several functions useful for registering (aligning) two images.
This is critical in remote sensing and medical imaging, for example. There are
functions for inferring various spatial transformations from control-point
pairs, for the subpixel adjustment of control-point pair locations, and for
normalized cross-correlation. There is also a graphical user interface (GUI) for
selecting control-point pairs in a pair of images.
