Dual-Tree Complex Wavelet Transform Based Audio Watermarking Using Distortion-Compensated Dither Modulation
This paper presents a local audio watermarking method based on the dual-tree complex wavelet transform (DT CWT) and distortion-compensated dither modulation (DC-DM).Specifically, we perform DT CWT on extracted audio segment, and embed the watermark signal in the decomposed low-pass coefficients.During the embedding process, the selected coefficient
