| 摘 要： | 三维图像中感兴趣目标的边界曲面的检测与重构是三维图像分析中的一个重要问题.本文提出了从三维图像中计算连续隐边界曲面离散采样点的新方法.基于这些计算得到的离散采样点及其灰度值,可以推导出更合适的等值面或者自适应曲面去近似表示三维图像中的连续隐边界曲面.

| Abstract: | Detecting and reconstructing continuous boundary surface of the object of interest in 3D images are important problems in 3D image analysis area.This paper proposes a new method to compute discrete sampling points for a continuous implicit boundary surface in a 3D image.Based on the discrete sampling points so computed and their gray values,more suitable isosurface or adaptive surface can be deduced to approximate the continuous implicit boundary surface. |

| Keywords: | 3D image continuous implicit boundary surface isosurface surface approximation |
