Abstract
A method for amending StirMark random geometric attacked watermarked images is introduced. The proposed scheme uses a reference image to identify the attacked pixels, then exchanges them for pixels from the original unwatermarked image. It is shown that the watermark can be successfully detected after the attacked image is corrected
