| 摘 要： | 介绍一种Bezier曲面片嵌入数字水印的新方法.对于由多段Bezier曲面片构成的曲面,每个Bezier曲面片通过四角的控制顶点,嵌入水印过程是将一个Bezier曲面片细分为两片.每一次细分在原始曲面片上将产生两个附加的顶点,通过曲面片细分使水印嵌入到曲面中.

| Abstract: | This paper presents a new method for embedding digital watermarks into Bezier surface patches.An object surface is supposed to be represented by multiple piecewise Bezier surface patches.A Bezier patch passes through its four-corner control points,to embed a watermark,a Bezier patch is divided into two patches.Since each subdivided patch shares two data points of the original patch,the subdivision apparently generates two additional data points on the boundaries of the original patch.The patch subdivision e... |
