A Curvature-based Approach for Multi-scale Feature Extraction from 3D Meshes and Unstructured Point Clouds
A framework for extracting salient local features from 3D models is presented in this paper. In the proposed method, the amount of curvature at a surface point is specified by a positive quantitative measure known as the curvedness. This value is invariant to rigid body transformation such translation and rotation. The curvedness at a surface position is calculated at multiple scales by fitting...

متن کاملConformal Alpha Shape-based Multi-scale Curvature Estimation from Point Clouds
Multi-scale geometrical and topological analyses of point clouds can reveal their rich structures. Because conformal alpha shapes of point clouds are hierarchical shapes under different mesh resolution or internal alpha values, their surface curvature estimations are one of the multi-scale geometrical analyses. We present a robust method for computing surface curvature of conformal alpha shapes...
متن کاملVoronoi-Based Estimation of Minkowski Tensors from Finite Point Samples
Intrinsic volumes and Minkowski tensors have been used to describe the geometry of real world objects. This paper presents an estimator that allows to approximate these quantities from digital images. It is based on a generalized Steiner formula for Minkowski tensors of sets of positive reach. When the resolution goes to infinity, the estimator converges to the true value if the underlying obje...
متن کاملFeature Estimation and Registration of Point Clouds in Reverse Engineering
Cultural relic is the carrier of information, such as production, life, science and technology, art and so on. However, due to natural and man-made reasons, artifacts are often destroyed. Excavation site is the most common variety of cultural relics, the need for cultural relics repair. Because the artifacts are generally made on the rotating disk, so the object of this study is the rotating de...
