摘    要:介绍了图像水印的BCH编码方式和水印信号的生成方法,在小波变换域内,采用多因子量化法实现了水印信号的嵌入、提取和图像水印的恢复,对该方法进行了试验,结果表明,该方法在水印的鲁棒性和不可见性之间实现了很好的折中,具有创新性,可靠性和实用性都很强。

关 键 词:数字水印  离散小波变换  BCH编码

Abstract:This paper introduces the BCH code of the image's gray value and the producing method of the watermarking signals, embeds and extracts the watermark ing signals and rebuilds the image watermarking using the multi-factors quantizi ng algorithms in the wavelet transform domain. At last,it demonstrates this meth od is right by some tests. These tests prove the method makes compromise between the robustness and the invisible of watermarking.It is novel and its credibilit y and practicality is good.
Keywords:Digatal watermarking  Discret wavelet transform  Bose-chaudhuri-ho cquenghem code(BCH)
