Methods and systems for dewarping images allow a user to reduce distortion in scanned images. A scanned image is processed using an optics model and an illumination model, and resampled to reduce distortion. The dewarping may be improved through iterative operations where a model parameter is varied. An optimal image is obtained which corresponds to a maximum metric as a measure of the quality of a resampled image.
