-
利用小波变换在时变信号的低频分解特性,提出了一种针对基音低频特性的水印嵌入算法,该水印具有良好的隐蔽性和对各种音频压缩算法的适应性,对于保护音乐作品知识产权具有较高的应用价值.
- Abstract:
-
Fundamental frequency is an important parameter in speech analysis. This paper studies elaborates a new watermark embed method. It uses discrete wavelet transform on the analysis of the fundamental frequency of the music. The experimental results show that the watermark embed through this approach is inaudible and robust against noise. It can be used as an effect copyright protected method of music masterpieces.
