Abstract :
A watermarking technique for copyright protection is introduced. It achieves a good improvement in the robustness of protected images, especially against attacks using JPEG compression. Simulation results demonstrate that the embedded watermarks can be almost fully extracted from images compressed with very high compression ratio.
