1. A method of registering a first volume with a second and different second volume, the method comprising:
- generating by a processor three two-dimensional (2D) signatures for the first volume where each corresponds to a different one of three orthogonal directions;
generating by the processor three 2D signatures for the second volume where each corresponds to a different one of the three orthogonal directions;
registering by the processor the 2D signatures of the first volume with the 2D signatures of the second volume for each same orthogonal direction to generate three transformations; and
registering by the processor the first volume with the second volume using the three generated transformations,wherein each pixel position of each 2D signature includes a minimum voxel intensity and maximum voxel intensity of a ray intersecting the corresponding 3D volume through the corresponding orthogonal direction and each 2D signature further includes rotation information and translation information of the corresponding 3D volume.

Abstract
Exemplary methods are provided. In one exemplary method, a lower-dimension signature is generated for each of a plurality of data sets of a given dimension. Registration is performed on the lower-dimension signatures. In another exemplary method, a two-dimensional signature is generated for each of a plurality of three-dimensional volumes. Registration is performed on the two-dimensional signatures.
