我们提出了一种稳健的、抗噪声的标准来表征二元体素对象中的平面骨架。它基于距离图和沿对象边界的测地距离。参数允许我们控制噪声灵敏度。如果需要,可以在第二步中使用改进的距离有序细化算法重建与原始对象的同伦。分析骨架以创建用于渲染的几何表示。通过合适的三角剖分方案将平面状零件转换为不包围体积的三角面。生成的表面比使用标准方法创建的表面具有更少的三角形数量,并且即使在以高抽取率进行简化之后也倾向于保持原始几何形状。我们的算法使我们能够交互式地渲染复杂 3D 结构的表现力图像,强调独立的平面和杆状结构。该方法用于骨活检微观结构的可视化。
We present a robust, noise-resistant criterion characterizing plane-like skeletons in binary voxel objects. It is based on a distance map and the geodesic distance along the object's boundary. A parameter allows us to control the noise sensitivity. If needed, homotopy with the original object might be reconstructed in a second step, using an improved distance ordered thinning algorithm. The skeleton is analyzed to create a geometric representation for rendering. Plane-like parts are transformed into an triangulated surface not enclosing a volume by a suitable triangulation scheme. The resulting surfaces have lower triangle count than those created with standard methods and tend to maintain the original geometry, even after simplification with a high decimation rate. Our algorithm allows us to interactively render expressive images of complex 3D structures, emphasizing independently plane-like and rod-like structures. The methods are applied for visualization of the microstructure of bone biopsies.
