Hole Filling in Images
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...
متن کاملHole Filling Through Photomontage
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 ...
متن کاملHole filling in 3D volumetric objects
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...
متن کاملA Hole-Filling Algorithm for Triangular Meshes
Data obtained by scanning 3D models typically contains missing pieces and holes. These can be caused due to scanning artifacts or artifacts in the surface due to wear and tear. We provide a method based on the Moving Least Squares projection to fill holes in triangular meshes obtained during the process of surface reconstruction . Our method can be applied to holes with non-planar geometry as w...
متن کاملArabic Retrieval Revisited: Morphological Hole Filling
Due to Arabic’s morphological complexity, Arabic retrieval benefits greatly from morphological analysis – particularly stemming. However, the best known stemming does not handle linguistic phenomena such as broken plurals and malformed stems. In this paper we propose a model of character-level morphological transformation that is trained using Wikipedia hypertext to page title links. The use of...
