Filling holes of 3D models is an important and complicated process. In this paper, we introduce a new and robust method for filling complex holes in triangular mesh models. In order to fill separate holes, the boundary edges of a hole are smoothly arranged and then locally uniform new points are added to the hole. The new points are selected by minimizing a hole filling area. The Delaunay trian...

Most hole filling approaches use techniques to fill up a hole first and then to smooth it. Very few tries rebuild features on the filled surface of the original 3D model. We propose an efficient hole-filling methodology which preserves sharp features of the geometry of the original model. The main idea is that we reconstruct feature curves in the missing parts of the given mesh before filling t...

In this paper we introduce an efficient hole-filling strategy for 3D meshes and at the same time aesthetically recover the sharp features of the original 3D model at the hole areas. Commonly, hole filling techniques try to fill up the hole first then smooth it. Very few have tried to recover the fine features of the original model at the holes. Our hole filling technique is different from other...

This project relates to automated 3D model generation of Urban Environments. Ground based modeling involves a setup of two 2D laser scanners, and a digital camera mounted on top of a truck. As we drive the truck in a city, the laser scans capture depth information using the LIDAR time-of-flight principle. These laser scans are then subjected to accurate localization and 3D data processing algor...

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 to automatically detect and adjust source ...

Due to the changes in viewpoint, holes may appear in the novel view synthesized by depth-image-based rendering (DIBR). A hole-filling method combining disparity-mapbased hole-filling and inpainting is proposed. The method first eliminates matching errors in destination image according to the disparity map. Then, holes are classified into different types according to their sizes. Finally, a disp...

The construction of hole filling (or hole segmentation) method for 3D volumetric images is a new challenging issue in computer science. It needs a geometrical approach since from a topological point of view 3D holes (tunnels) are not well-delimited subsets of three dimensional space. In this paper, the authors propose an original, efficient, flexible algorithm of hole filling for volumetric obj...

We show how to synthesize stereo images by adjusting camera separation to produce customized stereopsis and by changing the viewpoint to accommodate a head-tracked 3D display. We propose an improved method for stereo image synthesis from a pair of wide-baseline stereo images and corresponding disparity maps. To give proper depth in hole regions caused by disocclusion, we introduce a hole fillin...

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. First, a specific and comprehensive review of hole-filling techniques (as a relevant part in the field of mesh repairing) is carried out. We present a brie...
