| 摘要 | Reversible watermarking recovers an original image from a watermarked image by extracting the embedded watermarks. This work presents a reversible image watermarking approach that works on quantized DCT coefficients, implying that the original quantized image can be recovered perfectly after watermark extraction. The concept of zero replacement reversible watermarking is presented. Two parameters adjustment rules, ZRE and ZRX, are first proposed to embed and extract one bit to DCT coefficients, respectively. Additionally, the CA rule is presented to prevent confusion during embedding and extraction. Watermark embedding and extracting algorithms based on these three rules are then proposed. Experimental results indicate that the quality of watermarked image is very good, and that the proposed approach can also identify maliciously attacked regions efficiently. The proposed approach is also compared with other watermarking methods, demonstrating that the proposed approach works well. |
