A method registers a deformable image to a fixed image by first acquiring the deformable image and the fixed image. Multi-resolution multi-level image pyramids are generated for the deformable and fixed images. Levels of the multi-resolution multi-level image pyramids are processed in a coarse to fine order, and for each deformable and fixed image at each level partitioning the deformable and fixed image into overlapping blocks, and labeling each block with a label by solving, iteratively and in parallel, until a termination condition is reached, a binary maximum flow problem, within &#x3b1;-expansion, for each block and performing boundary fusion for the blocks, and then registering each block according to the labels to form the fixed image.

Method for deformable image registration

A method registers a source image with a target image, wherein the images are deformable, by first measuring dissimilarity between the source image and the target image. The dissimilarity minimized using a discrete energy function. At multiple scales, multi-scale Markov random field registration is applied to the source and target images to determine a deformation vector field. Then, the target image is warped according to the deformation field vector to obtain a warped target mage registered to the source image.
