基于SVD和Radon变换的抗旋转攻击盲水印算法
Blind watermarking algorithm against rotation attack based on SVD and radon transform
摘要
Abstract
In order to improve the robustness of traditional digital image watermarking based on Singular Value Decomposition (SVD), this paper proposes a watermarking scheme resisting to rotation attack based on Radon transform and SVD in wavelet domain. Wavelet transform is applied to the host image, then decomposes low frequency component of host image. It embeds the binary watermark image after affine transform scrambling into the singular value of the image. It uses odd-even quantization algorithm to embed watermark, which achieves embedding binary image blindly. Meanwhile before extracting watermark, it uses Radon transform detection algorithm to correct the text image, then watermark information is extracted. The experimental results demonstrate the proposed method is better than traditional algorithms based on SVD in commonplace signal processing, such as adding noise, filtering and JPEG compression etc. It is also robust enough for rotation attacks.关键词
