Perceptual-based DWPT-DCT framework for selective blind audio watermarking
A DWPT-DCT framework is used to perform variable-capacity blind audio watermarking. Balanced performance between robustness and imperceptibility can be achieved. A back-propagation neural network serves to seek suitable segments for watermarking. The proposed scheme can survive many DSP attacks including amplitude scaling.
