摘要
为评价遥感影像数字水印的有效性,本文在多目标决策TOPSIS方法的基础上,提出一种广义"有效性距离"评价模型,通过设计构造遥感影像数据数字水印有效性检测项和检测结果评价规则,实现对遥感影像数字水印有效性的数字量化,从而完成不同遥感影像数字水印有效性的显著性评价。仿真数据显示,该方法能够较直观、合理地区分不同遥感影像数字水印的有效性,可直接应用于地理信息数字水印技术的有效性和适用性评价。
In order to evaluate the effectiveness of digital watermarking applied in remote sensing image data,a concept of"effectiveness distance"is proposed,which is used to develop an evaluation model based on the multi-objective decision-making TOPSIS method.By defining and designing the test items’structure and its assessment rules,the effectiveness of digital watermark can be quantified,which makes it is very easy to present the significance of one from another.The simulation results show that the suggested method can distinguish different digital watermarks intuitively and reasonably based on"effectiveness distances",and can be directly applied to evaluate the effectiveness and applicability of digital watermarking technology in all kinds of geographic information data,besides remote sensing image.
