| 摘 要： | 针对嵌入式系统中,图像数字水印算法计算量较大的问题,设计了基于像素奇偶性的数字水印嵌入方法。通过分析原始像素的位置信息,选择像素块的边缘位置嵌入水印数据,减少了对原始图像的影响。与其他数字水印算法相比,在相同条件下,本文的方法计算量小,并具有较高的图像质量。

| Abstract: | To reduce the heavy operation of image watermarking algorithm in the embedded system, a kind of data hiding algorithm is clesiynel based on the parity of blocks. Through analyzing the locations of pixels, the algorithm selects the edge of the image to embed watermark data. The results show that the method has less amount of operation and better qualities than other algorithms under the same condition. |
