摘要
根据人的视觉特性,介绍了一种基于边缘检测的方法来检测图像的纹理区;方法简单、准确,且运算量小,有利于数字水印的不可见性和鲁棒性之间的平衡。
This paper introduces a method based on edge detection to detect the image texture; it is simple, precise, and only have a small amount of Computation. It is useful for the balance between invisibility and robustness of digital watermark.
