AIR (Automated Image Registration) is a program suite for volume-based image registration

Image registration

In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different coordinate systems....

The suite provides a number of programs for image registration with different transformation models, such as rigid-body, affine and nonlinear warping

Image warping

Image warping is the process of digital image editing such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting as well as for creative purposes ....
. For example, for affine transformation the registration from one brain scan to another may be found with the alignlinear program and written to the special air-file that stores the transformation matrix. The transformation may be inverted with the invert_air program and the volume may finally be resliced and interpolated with the reslice program.
