三维数字图像会遇到各种各样的问题，包括计算机断层扫描、生物建模、空间规划和计算机视觉。广泛的数据结构可用于此类图像的计算机表示。本文是一篇关于三维空间数据表示方法的综述教程，强调了应用于细胞（或基于体素的）图像的技术。我们试图通过比较它们的相对效率来统一这些图像中物体的内部、表面和结构信息的数据结构。本文还讨论了从序列分割图像中衍生出的高级表示，包括拓扑表示（欧拉特征和邻接树）、几何表示（边界、中间轴和特征）和空间组织表示（广义圆柱体和骨架）。
Three-dimensional digital images are encountered ma variety of problems, including computed tomography, biological modeling, space planning, and computer vision. A wide spectrum of data structures are available for the computer representation of such images. This paper is a tutorial survey of three-dimensmnal spatial-data representation methods emphasizing techniques that apply to cellular (or voxel-based) images. We attempt to unify data structures for representing interior, surface, and structural information of objects in such images by companng their relative efficmncy. The derivation of high-level representatmns from serial sectmn images is also discussed The representations include topological representations (Euler characteristic and adjacency trees), geometrical representatmns {borders, medial axes, and features), and spatial organization representations {generalized cyhnders and skeletons).
