The experiments with common image-processing operation on the watermarked image shows that the algorithm is quite robust.
对嵌水印图像作典型图像处理试验，表明该算法具有很好的鲁棒性。
As the image doesn't change during the process of watermark embedding, the watermarked image is same with the original image.
由于水印嵌入过程并不修改图像，所以水印图像与原始图像相同。
Watermark detection is implemented by comparing the new difference of mean values of watermarked image blocks with the threshold values.
在水印提取时，计算分块的新的均差值并与所设门限进行比较，从而检测嵌入的原始水印值。
