一個多分辨率的圖像水印方案

A SCHEME FOR MULTIRESOLUTION IMAGE WATERMARKING

  • 摘要: 圖像經(jīng)小波多級分解后，各子圖包含了原圖像的不同信息，通過用偽隨機實數(shù)修改中高頻細節(jié)子圖中較大的小波系數(shù)值，本文提出了一個基于小波變換的多分辨率靜態(tài)灰度圖像水印嵌入和檢測方案。對水印圖像進行退化處理模擬實驗表明，嵌入的水印具有很好的魯棒性。同時，水印的檢測僅需涉及到相關的幾個細節(jié)子圖，減少了計算量，加快了檢測速度。
    Abstract: Sub-images contain different information when the original image decomposed with wavelet. By modifying the larger wavelet coefficients of middle-high frequency range detail subimages with pseudo-random sequence of real numbers, the paper proposes a scheme for static gray image watermarking embedding and detection based on wavelet multiresolution transform. The experimental results show that the embedding watermarking is robust enough and the watermarking detection is only relevant to some detail sub-images, it simplifies and accelerates the algorithm.
