对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). a

All three, Discrete Wavelet Transform (DWT) - Singular Value Decomposition (SVD) and Adaptive Tabu Search (ATS) have been used as mathematical tools for embedding data into an audio signal. In this paper, we present a new robust audio waterma

数字水印嵌入算法，利用离散小波变换的（dwt）算法-Digital watermark embedding algorithm, using discrete wavelet transform (dwt) algorithm

基于dwt的视频数字水印源代码,使用小波变换，在视频中嵌入水印信息。-Dwt based video watermarking source code, the use of wavelet transform, the watermark is embedded in the video.
