| 摘 要： | 本文提出了一种用于遥感影像版权保护的可逆可见数字水印算法,利用像素比特位下移的方法保持水印覆盖区载体图像的重要视觉特性,并利用Huffman编码对水印及嵌入位置信息和图像低位面数据进行压缩存储,接收方无需任何有关水印的信息就能无损重建原始图像。实验证明,该算法可见度较高,可以将水印嵌入载体图像的任意位置,且不会出现亮度跳变,水印覆盖区呈半透明状,载体图像内容仍可粗略辨认,无论深色水印还是浅色水印,均具有较好的视觉效果。

| Abstract: | This paper presents a reversible visible digital watermarking algorithm for copyright protection of remote sensing image.To keep the important visual characteristics of image coverage area by using a bit-shift strategy to push down high bits,and uses Huffman coding to compress the low bits of carrier image and the information of watermark and its embedding position,the original image can be non-destructive reconstructed without knowing any information about the watermark on the receiving side.The results of... |
