Abstract

In this paper, we study a new strategy to embed watermarks to the scale subband of image wavelet transform domain. The coefficients in scale subband are much bigger than most coefficients in other subband. This means the coefficients in scale subband have higher perceptual capacity than coefficients in other subband to embed watermarks. We also use nonlinear wavelet transform derived from lifting scheme to get bigger scale subband coefficients. The experiment result shows the scheme is robust enough and the image watermarking algorithm using nonlinear wavelet transform is more robust than algorithms using usual wavelet transform.
