A DWT-DCT-Based Audio Watermarking Method Using Singular Value Decomposition and Quantization
2013
Journal of Signal Processing
In this paper, we propose an audio watermarking method in the discrete wavelet transform (DWT) and discrete cosine transform (DCT) domains using singular value decomposition (SVD) and quantization. In our proposed method, the original audio is initially segmented into nonoverlapping frames. Watermark information is embedded into the largest singular value of the DCT coefficients obtained from the DWT coefficients of each audio frame by quantization. Simulation results demonstrate that the
