Abstract

In this paper, a robust blind watermarking scheme using Multiple Descriptions (MD) is proposed. The watermark is embedded in the Wave Atom Transform domain by modifying one of the scale bands. The detection and extraction procedure do not need the original host image. We tested the proposed algorithm against nine types of attacks like JPEG compression, Gaussian Noise addition, Median Filtering, Salt and Pepper noise, etc. They are carried out using Matlab Software. The experimental results demonstrate that the proposed algorithms have great robustness against various imaging attacks.
