Abstract:
An image processing method for generating a projection of a source image, the method comprising the steps of:A. generating an intermediate image by a first affine transformation of the source image along a first axis relative to the source image, wherein said first transformation is executed by the steps of (1) selecting a plurality of coordinates for the intermediate image and (2) calculating for each of those selected coordinate a corresponding coordinate in the source image; B. generating a destination image by a second affine transformation of the intermediate image along a second axis relative to the source image wherein said second transformation is executed by the steps of (1) selecting a plurality of coordinates for destination image and (2) calculating for each of those selected coordinates a corresponding coordinate in the intermediate image; and C. generating a projection of the destination image along a selected one of the first and second axes.
