利用DFT变换实现数字水印的源代码，请大家赐教-the code about the digital watermark in the region of DFT，using matalab

基于傅里叶变换的数字水印算法，在原始图像的傅里叶变换域中对称的嵌入数字水印信息-Fourier transform-based digital watermarking algorithm, the original image of the Fourier transform domain, the embedded digital watermark information symmetry

实现在语音的DFT域内嵌入水印信息，使用平衡GOLD序列作为扩频码。-Realization of the embedded watermark information in the voice of the DFT domain，balance GOLD sequence as the spreading code
