Ab Initio Study Of Zno-Based Gas-Sensing Mechanisms: Surface Reconstruction And Charge Transfer
, 2009 Density functional theory (DFT) calculations were employed to explore the gas-sensing mechanisms of zinc oxide (ZnO) with surface reconstruction taken into consideration. Mix-terminated (10 (1) over bar0) ZnO surfaces were examined.

Surface reconstruction: GNCs and MFA
Proceedings of IEEE International Conference on Computer Vision, 2002 Noise-corrupted signals and images can be reconstructed by minimization of a Hamiltonian. Often the Hamiltonian is a non-convex functional. The solution of minimum energy can then be approximated by the Graduated Non-Convexity (GNC) algorithm developed for the weak membrane by Blake and Zisserman. The GNC approximates the non-convex solution space by a

Point Cloud Upsampling for Accurate Surface Reconstruction via Attention-Guided Generation
IEEE AccessReconstructing accurate surfaces from sparse point clouds remains a fundamental challenge in 3D vision. In this paper, we propose a novel upsampling framework, called Surf-PU, that focuses on surface-aware point generation.

Robustness Issues in Surface Reconstruction [PDF]
, 2001 The piecewise linear reconstruction of a surface from a sample is a well studied problem in computer graphics and computational geometry. A popular class of reconstruction algorithms filter a subset of triangles of the three dimensional Delaunay triangulation of the sample and subsequently extract a manifold from the filtered triangles.

Parallel and Deterministic Algorithms for MRFs: Surface Reconstruction and Integration
, 1989 In recent years many researchers have investigated the use of Markov random fields (MRFs) for computer vision. The computational complexity of the implementation has been a drawback of MRFs.
