NeurCADRecon: Neural Representation for Reconstructing CAD Surfaces by Enforcing Zero Gaussian Curvature
ACM Transactions on Graphics (TOG), Volume 43, Issue 4Article No.: 51, Pages 1–17https://doi.org/10.1145/3658171Despite recent advances in reconstructing an organic model with the neural signed distance function (SDF), the high-fidelity reconstruction of a CAD model directly from low-quality unoriented point clouds remains a significant challenge. In this paper, ...

Curvature-Driven Conformal Deformations
ACM Transactions on Graphics (TOG), Volume 43, Issue 4Article No.: 139, Pages 1–16https://doi.org/10.1145/3658145In this paper, we introduce a novel approach for computing conformal deformations in ℝ3 while minimizing curvature-based energies. Curvature-based energies serve as fundamental tools in geometry processing, essential for tasks such as surface fairing, ...

K-Surfaces: Bézier-Splines Interpolating at Gaussian Curvature Extrema
ACM Transactions on Graphics (TOG), Volume 42, Issue 6Article No.: 210, Pages 1–13https://doi.org/10.1145/3618383K-surfaces are an interactive modeling technique for Bézier-spline surfaces. Inspired by k-curves by [Yan et al. 2017], each patch provides a single control point that is being interpolated at a local extremum of Gaussian curvature. The challenge is to ...

A Scale Invariant Interest Point Detector for Discriminative Blob Detection
IbPRIA '09: Proceedings of the 4th Iberian Conference on Pattern Recognition and Image AnalysisJune 2009, Pages 233–240https://doi.org/10.1007/978-3-642-02172-5_31In this paper we present a novel scale invariant interest point detector of blobs which incorporates the idea of blob movement along the scales. This trajectory of the blobs through the scale space is shown to be valuable information in order to ...

Surface Parameterization in Volumetric Images for Feature Classification
BIBE '00: Proceedings of the 1st IEEE International Symposium on Bioinformatics and Biomedical EngineeringNovember 2000, Page 297Curvature-based surface features are well suited for use in multimodal medical image registration. The accuracy of such feature-based registration techniques is dependent upon the reliability of the feature computation. The computation of curvature ...
