中文摘要: 为降低水印检测的虚警率和漏警率,提出一个泛化盲检测模型。通过在Matlab环境下的实验,遴选7个数字水印检测算法,采用顺序检测法对待检测图像进行检测,然后利用数据融合法综合分析检测结果,判断其中的水印信息。相对单个算法来说,泛化检测模式的检测效率更高,检测耗费时间大为缩短,对仿真实验所采用的17个数字水印嵌入系统进行检测,达到虚警率为5.495%,漏警率为1.648%,正确检测率为92.857%的结果。经过检测分析,泛化检测模型还对适度的剪切、拉伸、反色、旋转以及几何失真等攻击具有更高的抵抗能力。因此,该泛化检测模型具有较高的可行性。
Abstract:A blind watermark detecting model was proposed to reduce the false alarm rate and the miss alarm rate on detecting. With Matlab software,image samples were detected by 7 different digital watermark detecting mothods one by one, whose detected results were analysed by data fusion method to discriminate the watermark information in the images.Compared by a single algorithm, the pan methods discussed can shorten testing time and improve dectecting efficiency. When 17 digital watermark embedded systems were detected in the simulation experiment, the false alarm rate was 5.495%,the miss alarm rate was 1.648%,the validity rate reached 92.857%. In addition, the methods discussed is less vulnerable to attacks of certain. In a word, the methods discussed has more feasibility than a single algorithm.
