Information retrieval in digital watermarking.

Information retrieval in digital watermarking.

Digital watermarking, the art of robust information hiding in images, has gained a large interest in both research and industry in the past few years. Every watermarking system has two main parts: watermark embedding and watermark extraction/detection. Previous developments in the theoretical analys...
