Abstract
A method of reconstructing an original image from a printed and scanned image includes determining a plurality of transformation parameters including a rotation a of the scanning grid relative to the printing grid and a plurality of translation parameters which give a position of a node on the printing grid in a coordinate system of the scanning grid, generating a system of non-linear equations which represent the printed and scanned image as a function of: (i) the original image, (ii) a print/scan resolution ratio, and (iii) the transformation parameters, computing coefficients for the system using the resolution ratio, the transformation parameters and the given print model, generating a linear approximation of the system of non-linear equations, solving the linear approximation for an approximation of the original image, and creating a reconstructed original image from the approximation of the original image.
