The geometrical attacks are still a problem for
many digital watermarking algorithms at present. In this paper, we propose a watermarking algorithm for color images resistant to geometrical distortions (rotation and scaling). The singular value dec

This paper proposes new watermarking technique
based on tetrolet domain. The tetrolet transform is a new
adaptive Haar-type wavelet transform based on tetrominoes. It
avoids Gibbs oscillation because it applies the Haar function at
the edge o
