摘要：

In this paper, we propose a normalization-based robust image watermarking scheme using nonsubsampled contourlet transform. Applying nonsubsampled contourlet transform for the normalization image, we select the middle frequency subbands for watermark embedding using spread spectrum technique. The experimental Simulation results show higher imperceptibility and robustness against several common watermarking attacks and geometrical attacks.
