3D Planar Representation of Stereo Depth Images for 3DTV Applications
Ozkalayci, Burak O.; Alatan, Abdullah Aydın (2014-12-01)
The depth modality of the multiview video plus depth (MVD) format is an active research area, whose main objective is to develop depth image based rendering friendly efficient compression methods. As a part of this research, a novel 3D planar-based depth representation is proposed. The planar approximation of multiple depth images are formulated as an energy-based co-segmentation problem by a Markov random field model. The energy terms of this problem are designed to mimic the rate-distortion tradeoff for a...
3D finite element modeling of surface excavation and loading over existing tunnels
Kaçar, Onur; Erol, Orhan; Department of Civil Engineering (2007)
The influence of the surface excavation and loading on the existing tunnels has been investigated using a Finite Element Method program, Plaxis 3D Tunnel. A parametric study has been carried out where the parameters were the depth of the surface excavation, the eccentricity of the excavation with respect to the tunnel axis, the height of the embankment fill and the stiffness of the soil. It is found that, excavations over the existing tunnels have a negative effect on the tunnel lining capacity since the un...

3D reconstruction of rigid objects from multiple calibrated views
Mülayim, Adem Yaşar; Atalay, Mehmet Volkan; Halıcı, Uğur; Department of Computer Engineering (2003)
In this thesis, an image based three dimensional (3D) model reconstruction system is investigated and the work done for such a complete reconstruction system is presented. Calibrated images of a rigid object, acquired under a simple but controlled environment, are used to recover the 3D object geometry and the surface appereance. Based on a multi-image camera calibration method, an algorithm to define the rotation axis of a turn-table with respect to the fixed camera coordinate frame has been developed. Fur...
3D numerical modeling of boiling in a microchannel by arbitrary Lagrangian-Eulerian (ALE) method
Jafari, Rahim; Okutucu Özyurt, Hanife Tuba (2016-01-01)
The arbitrary Lagrangian-Eulerian method (ALE) is used to model the hydrodynamics and the heat transfer of an elongated vaporized bubble in a rnicrotube. The Navier-Stokes equations along with the energy equation are solved in ALE description as a single fluid with two subdomains and a moving mesh at the interface of the liquid and the vapor phases. The numerical framework is the commercial CFD code COMSOL multiphysics with the finite element method, which has been improved by external functions to the phas...
