| 摘 要： | 针对图像水印的鲁棒性,运用协同序参量理论,提出一种基于协同序参量的定量评价方法。对载体图像完成各类鲁棒性实验,计算比较了各模式的协同序参量初始值,使用序参量演化曲线进行验证,得到相应的鲁棒性定量评价。评价结果与相关系数法一致,但更加方便和实用。

| Abstract: | Aimed at image watermark robustness, an evaluative method based on synergetic order parameter and its usage was first advanced. Many kinds of robust experiment of Image carrier were done. After procession, the synergetic original order parameter of patterns in the set were calculated and compared. Through validation by the order parameter evolvement curves, their robust conclusions were gotten. This method is more convenient and applied than the correlative coefficient method, although the two methods have same conclusion. |
