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

Line-preserving hole-filling for 2D-to-3D conversion
Proceedings of the 11th European Conference on Visual Media Production, 2014Many 2D-to-3D conversion techniques rely on image-based rendering methods in order to synthesize 3D views from monoscopic images. This leads to holes in the generated views due to previously occluded objects becoming visible for which no texture information is available.

Selective hole-filling for depth-image based rendering
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2015One of the biggest challenges in view interpolation is to fill the regions without projective information in the synthesized view. In this paper, we present a new approach that identifies and corrects different types of missing information. In the first stage, we propose a fast solution to tackle the problems of cracks and ghost, common artifacts in ...

The halving method in the hole-filling problem
USSR Computational Mathematics and Mathematical Physics, 1988Abstract The important practical problem of minimizing the function of two variables V(x, y) = [G(y) − G(x) + C] (y − x) , C ⩾ 0, y⩾x , is considered where G ( z ) has a unimodal piecewise continuous derivative. An algorithm which makes essential use of the halving method is devised, with a labour content estimate O ( ln ( u / e )), where

An Efficient Hole-Filling Approach Using Adaptive Rendering
2012 Sixth International Conference on Genetic and Evolutionary Computing, 2012Based on depth image based rendering (DIBR), this paper presents an efficient hole-filling approach using adaptive rendering for the 2D-to-3D conversion system, i.e., converting monocular image to multi-view virtual images. the traditional processing of DIBR includes depth map pre-processing, image 3D warping, and hole-filling.

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 ...
