Abstract : Lossy compression is inherently contradictory with watermarking and makes the watermark retrieval unreliable. In this paper, we propose a watermarking technique capable to correctly retrieve watermark in both image and video, where watermarking is combined with JPEG/MPEG compression standards to adaptively obtain a proper trade-off among imperceptibility, achievable embedding capacity and robustness to lossy compression. Experimental evaluation demonstrates that algorithm achieve imperceptible watermark with error-free extraction performance and sufficient embedding capacity in the presence of lossy compression.
