A Visible Watermarking Algorithm Holding Image Content
-
摘要: 根据图像的噪声掩蔽性设计了一种小波域可见水印算法,并根据水印图像的纹理特征对算法作了进一步改进。在此基础上,提出了具有内容保持的嵌入策略及改进算法。实验结果表明,该算法在保证水印具有较好可见性的同时,载体图像内容得到了保持。Abstract: A wavelet visible watermarking algorithm is proposed based on noise masking,then the improvement is made based on texture feature of watermark image.Based on the(above) idea,an image content holding strategy and the algorithm are proposed.Experimental results have showed that the proposed algorithms can ensure watermark visibility and the loss in host image become less.
