Cluster Analysis Based Robust Mesh Watermarking Approach
一种基于聚类分析的三角网格强壮水印方法

We presented a cluster analysis based robust watermarking approach which can be used for watermark embedding and extraction of triangle mesh,a frequently research object in computer graphics.For the first time,we applied K-Means cluster method,which is a common method in cluster analysis,into mesh watermarking research.Watermark information was embedded by spherical triangulation of cluster result and subtle modification of facet normals.By analyzing characters of the whole process,the high efficient numeri...
