The principles of global threshold and dynamic threshold and the proposed image segmentation method are presented and the image processing results are compared.

介绍了全局阈值法、动态阈值法、全局阈值结合动态阈值法的算法原理，并比较了以上三种方法的缺陷分割效果。

Experimental results show that the proposed scheme is robust for some image processing operations such as lossy JPEG compression, low pass filtering, median filtering and cropping.

实验结果表明水印是不可察觉的，经过JPEG有损压缩、低通与中值滤波、剪切等图像处理操作后仍是鲁棒的。
