ABSTRACT:
A method of processing image data is described. The method comprises receiving first image data corresponding to a first image and second image data corresponding to a second image, wherein pixels of the first image data and pixels of the second image data are registered to each other. The method also comprises shifting at least a portion of the first image data by a first fractional pixel displacement and at least a portion of the second image data by a second fractional pixel displacement to generate first shifted data and second shifted data, respectively. The method also comprises interpolating the first shifted data and the second shifted data to generate first interpolated data and second interpolated data, respectively. The method further comprises differencing the first interpolated data and the second interpolated data to generate residue data. An image processing system comprising a memory and a processing unit configured to carry out the above-noted steps is also described. A computer-readable carrier adapted to program a computer to carry out the above-noted steps is also described.
