本文提出了一种新颖的三维 (3D) 花卉建模技术，该技术利用 X 射线计算机断层扫描 (CT) 系统和真实世界的花卉。尽管 CT 系统提供了捕获花朵内部结构的体数据，但很难将它们准确地分割成特定器官的区域并将其建模为光滑的表面，因为花朵由彼此接触的薄器官组成。因此，我们引入了一种半自动建模技术，该技术基于一种新的活动轮廓模型，具有专为花卉 CT 设计的能量泛函。我们的关键思想是通过两个重要的基元（轴和片）来近似花的组成部分。基于我们的活动轮廓模型，我们还提供新颖的用户界面和数值方案来拟合这些基元，以便有效地重建逼真的薄花器官。为了证明我们技术的可行性，我们提供了从 CT 体积重建的各种花卉模型。
This paper presents a novel three dimensional (3D) flower modeling technique that utilizes an X-ray computed tomography (CT) system and real-world flowers. Although a CT system provides volume data that captures the internal structures of flowers, it is difficult to accurately segment them into regions of particular organs and model them as smooth surfaces because a flower consists of thin organs that contact one another. We thus introduce a semi-automatic modeling technique that is based on a new active contour model with energy functionals designed for flower CT. Our key idea is to approximate flower components by two important primitives, a shaft and a sheet. Based on our active contour model, we also provide novel user interfaces and a numerical scheme to fit these primitives so as to reconstruct realistic thin flower organs efficiently. To demonstrate the feasibility of our technique, we provide various flower models reconstructed from CT volumes.
