基于外延特征的柵格地圖噪聲去除算法 - The algorithm takes advantage of the merits of the watermarks both in low frequency and high frequency and can embed more information with less distortion . experimental results show the algorithm is robust to many common image operations . as for the vector map data , an uniform model of embeding watermark for vector maps and raster maps is proposed after current trend of research and watermarking methods of 3 - d vector images are summarized , primary study results show the model is effective and promising to further research
目前該問題在國內(nèi)外都還處于探索階段，作者在分析了國內(nèi)外三維矢量水印的研究狀況、研究方法后，提出了將矢量數(shù)據(jù)中的部分信息轉(zhuǎn)化為柵格形式后再嵌入水印的方法，該方法使地圖柵格數(shù)據(jù)和矢量數(shù)據(jù)在嵌入水印時(shí)能夠使用統(tǒng)一模型，初步的實(shí)驗(yàn)結(jié)果表明該方法為二維地圖矢量數(shù)據(jù)的水印嵌入開辟了一種新途徑。
