A New Novel Hybrid SVD-DCT Watermarking

摘要：

In this paper, a new watermarking method which combines with the singular value decomposition (SVD) and based on DCT (discrete cosine transform) multispectal image is presented. We use DCT transform, zig-zag order, padding zeroes and inverse DCT transform to obtain four different frequency images. Watermarking is embedded in low frequency by singular value decomposition. So the watermarked image has good transparency and robustness. Experimental shows that the watermarking performs well in against many attacks.
