Claim 10:
11. A system comprising:
a processor; and
a local memory operable to store a plurality of machine readable instructions which when executed by the processor are operable to cause the system to perform steps comprising:
receiving a pair of images;
defining a parametric deformation model providing an image deformation for each of a set of deformation parameters;
defining a loss function based, at least in part, on at least one directional gradient of each of a processed pair of images obtained from the received pair of images by a process comprising applying the parametric deformation model, wherein the loss function is minimized when the pair of images are aligned; and
performing a multi-scale search to determine an optimal deformation parameter that minimizes the loss function;
wherein the optimal deformation parameter defines an alignment of the pair of images.
