FFT-based techniques are actively used to register 2-D images, i.e., to find the shift, rotation, and scaling necessary to align one image with the other. It is desirable to extend these techniques to the problem of registering 3-D images. Registration of 3-D images is an important problem in areas such as bioinformatics (e.g., in protein docking) and geoinformatics (e.g., in earth modeling).
