介绍了矢量图数字水印的基本要求,并对二维矢量图数字水印技术进行了分析、比较。二维矢量图数字水印主要采用基于特征集合的方式进行水印信号的嵌入,其关键是对矢量图进行特征分析,并找出好的模型表达方式。
This paper discussed the basic require about the digital watermarking of two-dimensional vector graph and the algo- rithm of digital watermarking. The watermarking mainly selected the method which gathered based on the characteristic to carry on the watermark signal inserting, its key was carries on the characteristic analysis to the vector graph, and discovered the good model expression way.
