Feature Sensitive Hole Filling with Crest Lines
2006Feature sensitive hole filling is important for many computer graphics and geometric modeling applications. In this paper, we address the problem of reconstructing the salient features when filling holes in mesh. It respects fine shape features and works well on various types of shapes, including natural mesh and mechanical parts.

An efficient and collision-free hole-filling algorithm for orthodontics
The Visual Computer, 2013Hole filling of teeth and gums is an essential stage in orthodontics after segmentation. The patching mesh should keep the morphological features of generic teeth and gums while avoiding collision between two adjacent teeth. This paper presents an efficient hole-filling algorithm to reconstruct the missing part of teeth and gums.

Fast MRF-Based Hole Filling for View Synthesis
IEEE Signal Processing Letters, 2018Hole filling is one of the key issues in generating virtual view from video-plus-depth sequence by depth-image-based rendering. Hole filling method based on Markov random fields (MRF) is a practical way for view synthesis, but the traditional ones might introduce some foreground textures to the hole regions, and suffer from high computational ...

Research on depth hole filling algorithm based on Kinect
2017 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2017The depth image obtained by Kinect usually exists cavities at the edge of the object and occlusions. For this problem, many scholars have put forward many solutions. The existing cavity filling algorithms can repair the holes effectively, but these algorithms have a long execution time and are difficult to apply in practical applications.

A survey on algorithms of hole filling in 3D surface reconstruction
The Visual Computer, 2016The surface reconstruction of 3D objects has attracted more and more attention for its widespread application in many areas, such as computer science, cultural heritage restoration, medical facilities, entertainment. However, due to occlusion, reflectance, the scanning angle, raw data preprocessing, it is inevitable to lose some point data, which leads

A new hybrid approach for view extrapolation and hole filling
2013 IEEE International Conference on Consumer Electronics (ICCE), 2013Generating high quality synthesized views is key factors in the successful adoption of multiview and stereoscopic 3D TV technology. One of the main issues regarding synthesized views is the occluded regions which appear as holes in the virtual views. Filling these holes is even more challenging when only one view is available and other views need to be

Direction hole-filling method for a 3D view generator
International Journal of Computational Science and Engineering, 2015Depth image-based rendering DIBR technology is an approach to creating a virtual 3D image from one single 2D image. A desired view can be synthesised at the receiver side using depth images to make transmission and storage efficient. While this technique has many advantages, one of the key challenges is how to fill the holes caused by disocclusion ...

An effective method for hole filling in 3D triangular meshes
2018 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT), 2018We present an effective method for filling holes in 3D triangular meshes based on the direct solution of Laplace and biharmonic partial differential equations. Initial mesh required for the triangulation of the hole region is computed by using a hybrid method that combines 2D triangular mesh generation and biharmonic-spline surface fitting ...

Directional adaptive hole filling for new view synthesis
2012 IEEE International Conference on Consumer Electronics (ICCE), 2012In this paper, a new hole filling method based on the direction of background image texture for new image view synthesis is presented. Strong texture gradient of background pixel is traced along its direction to obtain the texture orientation. Then texture direction map is computed for the hole pixels, based on the texture orientation.
