An important problem constraining the practical implementation of robust watermarking technology is the low robustness of existing algorithms against geometrical distortions. An adaptive blind watermarking scheme util...
A new image watermarking scheme is proposed to resist rotation, scaling and translation (RST) attacks. Six combined low order image moments are utilized to represent image information on rotation, scaling and transl...
