摘要:
<正> 基于体元的三维物体表示与分析在许多科学领域,尤其是医学领域中,有重要的应用前景。在三维图象中物体的表示和处理可归结为基于表面和基于体积的两大类方法。在这方面,尽管已有许多工作,然而只是在表示和处理方法上强调效率,而对于三维物体的表示的精度和数据压缩、显示的质量等方面还做得不够,往往丢失了一些在医学应用中有意义的细微部分。本文从改善三维图象中物体的表面提取方法和提高表面表示的精度出发,提出用一种k
Abstract:
In this paper an approach of the surface representation of voxelbased object is presented. Based on the basic topological properties, an object definition and some useful properties are given, and a k-tree based system for surface extraction, representation and display is proposed. Two local operators are developed and surface representation is obtained by the tree’s travelling of the two operators. Some experimental results show that this method has the advantages of precision of representation and of quality of display.
