Experimental results show the watermark is invisible and robust to common image processing operations such as JPEG compression, cropping, resizing, median value filtering and noise perturbation.

实验证明，水印具有不可见性，对通常的图像处理，如JPEG压缩、剪切、缩放、中值滤波等以及噪声干扰都具有很强的鲁棒性。

Experimental results prove that the method is invisible and robust enough against some image degradation processes such as resizing, cropping, JPEG or JPEG2000 compression.

实验结果表明，该算法不仅具有较好的透明性，而且对缩放、剪切、JPEG或JPEG2000压缩等图像退化处理或攻击均具有较强的鲁棒性。

We test the algorithm performance in the cases of single watermark, double watermarks and multi watermarks when different distortions such as JPEG compression, image resizing and cropping are applied.

该文就单水印，双水印以及多水印情形进行了仿真并进行JPEG压缩、图像缩放、剪切等失真测试。
