1. A method for producing resampled images from original images comprising: determining a plurality of sampled values of a two-dimensional filter based on a specified geometric transformation, a pixel spacing of an original image, and a spatial quantization factor for the pixel spacing of the original image; for each pixel of a resampled image, computing an identifier that indicates a position, within the original image, for the two-dimensional filter; and generating the resampled image by selectively applying portions of the plurality of sampled values of the two-dimensional filter to the original image, wherein the selected portions of the plurality of sampled values are based on pixel locations of the original image relative to the positions for the two-dimensional filter indicated by the computed identifiers.
