【摘要】 为了进行医学二维图像的三维表面图像重建,最重要的一步就是提取二维图像的轮廓线。文章首先从算法的角度上探讨了诸如线性加权平均的图像插值方法、动态弹性插值方法、方向性插值方法和基于形状的插值算法的基本原理,以及它们的适用范围和局限性。在基于形状的插值方法的基础上,提出了改进的轮廓插值加权算法,采用这种改进算法以后,三维重建的轮廓质量有明显的改善。更多还原

【Abstract】 For the surface of 3D reconstruction from 2D medical imaging ,it is very important to pickup 2D imaging outline.In this paper,several basic principles,such as linearity weight average?dynamic fliexibility?direction and arithmetic based on fiqure insert value,are discussed.Their application range and localization are also introduced.According to the shape of insert value,the improved algorithm of outline insert value is formed in this paper.As a result,it obviously improves the new arithmetic.更多还原
