A comparison of hole-filling methods in 3D [PDF]

International Journal of Applied Mathematics and Computer Science, 2016
This paper presents a review of the most relevant current techniques that deal with hole-filling in 3D models. Contrary to earlier reports, which approach mesh repairing in a sparse and global manner, the objective of this review is twofold.

A Fast Hole-Filling Method for Triangular Mesh in Additive Repair

Applied Sciences, 2020
In the triangular meshes obtained in additive repair, it is a challenge to find one single hole-filling method to close all holes and make the filling patches assort with surrounding meshes well with low time complexity, which is mainly caused by the ...

Hole filling with oriented sticks in ultrasound volume reconstruction. [PDF]

J Med Imaging (Bellingham), 2015
Volumes reconstructed from tracked planar ultrasound images often contain regions where no information was recorded. Existing interpolation methods introduce image artifacts and tend to be slow in filling large missing regions. Our goal was to develop a computationally efficient method that fills missing regions while adequately preserving image ...

Survival of the metallic state in a single-hole multiband p-orbital molecular system [PDF]

Nature Communications
Strong correlations and ferromagnetic Hund’s coupling lead to diverse electronic phenomena in transition-metal oxides that sensitively depend on the d-orbital electron filling.

Hole Filling of Single Building Point Cloud Considering Local Similarity among Floors

Remote Sensing, 2022
In the process of acquiring a point cloud, due to the shielding of the building itself and other ground objects (such as vegetation), the collected point cloud cannot cover the building facades surface uniformly and completely, and can produce several ...

Hole-Filling for DIBR Based on Depth and Gradient Information

International Journal of Advanced Robotic Systems, 2015
Depth image-based rendering (DIBR) is a method for generating new virtual images from known viewpoints. However, holes often appear in the rendered virtual images due to occlusion and inaccurate depth information.

Hole Filling Through Photomontage [PDF]

Procedings of the British Machine Vision Conference 2005, 2005
To fill holes in photographs of structured, man made environments, we propose a technique which automatically adjusts and clones large image patches that have similar structure. These source patches can come from elsewhere in the same image, or from other images shot from different perspectives. Two significant developments of this work are the ability

DEM Study of Seed Motion Model-Hole-Wheel Variable Seed Metering Device for Wheat

Agriculture, 2022
On the basis of the discrete element method (DEM), the movement of seed particles during the filling process of a wheat hole-wheel variable seed-metering device was numerically simulated. The impact of various model hole structures, filling postures, and
