A Novel Scrambling Digital Image Watermarking Algorithm Based on Contourlet Transform

Digital watermarking technology is a very good method for protecting copyright. A novel image watermarking scheme based on contourlet transform is proposed. The original carrier image was executed in contourlet transform and four directions of the second level subband were marked, afterwards, the sc...

More Information
Summary:Digital watermarking technology is a very good method for protecting copyright. A novel image watermarking scheme based on contourlet transform is proposed. The original carrier image was executed in contourlet transform and four directions of the second level subband were marked, afterwards, the scrambled digital watermarking is embedded in them. The experimental results show that the proposed watermarking scheme is feasible and simple. The embedded watermarking images have tiny difference with the original images and the extracted watermarking is accurate. It is imperceptible and robust against various signals processing such as noise adding, rotating, altering, cropping, compression, brightness variations and mosaic, etc.
