一種DWT與DCT結(jié)合的盲音頻水印算法
A blind audio watermark algorithm base on dwt and dct
-
摘要: 該文提出了一種新的盲音頻水印算法。它充分利用離散小波變換的多分辨率特性和離散余弦變換的能量壓縮能力,通過量化處理把降維后的二值圖像水印嵌入到原始的音頻信號中,在水印的提取過程中不需要原始音頻信號的參與。仿真實驗證明了算法的魯棒性和不可感知性。Abstract: This paper presents a novel blind audio digital watermark algorithm. It makes full use of the multi-resolution of DWT and the energy compression of DCT and embeds binary image watermark in the audio by quantification process. The watermark can be extracted without the original audio signal. Experimental results demonstrate the algorithm is robust and imperceptible.
