A Novel Watermarking Method using Hadamard Matrix Quantization
Abstract. One of the most used watermarking algorithms is Singular Value Decomposition (SVD), which has a balanced level of imperceptibility and robustness. However, SVD uses a singular matrix for embedding and two orthogonal matrices for…
