摘要

提出了一种二维电子海图自适应水印技术，利用平移不变策略，获得海图空间内频域较稳定的一个水印嵌入载体集合。为了防止水印嵌入幅度过大而影响海图使用和从水印算法的安全性考虑，提出了灰度平衡控制方案，计算每个划分好的矩形区域内可嵌入水印的最大容量。实验表明，该方法能够适应海图常规操作所带来的数据扰动，具有较好的顽健性。

Abstract

An adaptive watermarking technology for 2D electronic charts was proposed. It took count in the discrete wavelet domain scheme

and obtained an ideal embedding set for watermarks in the electronic chart space. In order to preserve topology of map effectly by the large embedding rates and protect the safety of watermarking scenario

a gray balance means was provided

and the maximum capacity in each divided rectangle blocks in the electronic charts was computed.The experiment also shows that it can adapt to data perturbation by conventional operations.The method has better robustness.
