A Robust Image Watermarking Algorithm Based on SVD
Jian Chen · Jisuanji gongcheng · 2004
This paper proposes a watermarking algorithm based on singular value decomposition (SVD), which is robust to common distortions. The watermark, consisting of random numbers according to the standard normal distribution, is embedded into images singular values. Experimental results show thai the watermarking algorithm performs well in robustness. The embedded watermark can be detected reliably, following usual signal processing and JPEG compression. Specially, the watermarking algorithm is robust to geometric distortions, such as transpose, mirror reflection, right-angle rotation, scale, and translation.
