A digital audio watermark embedding algorithm with WT and CCT

摘要

This paper propose an audio digital watermarking algorithm based on the wavelet transform (WT) and the complex cepstrum transform (CCT). The algorithm realized to embed a binary image watermark into the audio signal and improved the imperceptibility of watermarks. Experimental results show that this algorithm has a better robustness against common signal processing such as noise, filtering, resampling and lossy compression.
