1. A method for biometric image alignment, comprising: receiving an input image of a biometric object; identifying a plurality of sets of candidate transformations, wherein each set of candidate transformations included in the plurality of sets of candidate transformations aligns the input image to a different enrollment image included in a plurality of enrollment images; grouping the plurality of sets of candidate transformations into a combined set of candidate transformations; selecting a subset of candidate transformations from the combined set of candidate transformations; and identifying a first transformation based on the selected subset of candidate transformations, wherein the first transformation aligns the input image to a first enrollment image included in the plurality of enrollment images.
