| 摘 要： | 提出了一种新的针对彩色图像的盲水印算法。算法通过在彩色图像空域中嵌入形状和排布都比较规则的锚点来标记图像中嵌入水印的位置,从而在图像经过缩放裁剪等几何变换后仍然能够比较容易地找到水印嵌入的准确位置。实验表明算法对色彩和几何变换都有良好的鲁棒性。

| Abstract: | This paper presents an innovative blind watermark algorithm for colour images.This algorithm marks the embedded watermark region size and position through embedding some blocks with regular shape and arrangement called anchor point in colour image spatial domain.By doing this,precise position of embedded watermark can be easily extracted after cropping and scaling operation being done onto the image.Experimental results show that such algorithm is robust to the colour adjusting and geometry transforming. |
