Uniform discrete Fourier transform (DFT) has the drawback of public frequency points. On the other hand, nonuniform discrete Fourier transform (NDFT) could set up random sampling points in frequency domain as desired rather than fixed frequency points in DFT. That is DFT is the special condition of NDFT. This paper utilizes NDFT to instead uniform DFT in the algorithm of audio watermarking scheme with the purpose of providing the probability of hidden embedding positions. Moreover, to further… CONTINUE READING
