Research of Digital Image Watermarking Robustness Algorithm Based on DCT
2014
Image watermarking is a carrier image watermarking technology. This paper studies the research direction of the digital watermarking image of the DCT-based image robust watermarking algorithm design. We studies robust algorithm of watermarking image on specific design and implementation process based on DCT domain, the process including image watermarking embedding and watermarking extraction and watermarking detection. Experimental results achieved watermarking embedding evaluation requirements: effectiveness, transparency and robustness.
