A geometry-based multi-view video coding (MVC) method is proposed. In order to utilize the spatial redundancies between multiple views, the scene geometry is estimated as dense depth maps. The dense depth estimation problem is modeled by using a Markov random field (MRF) and solved via the belief propagation algorithm. Relying on these depth maps of the scene, novel view estimates of the intermediate views of the multi-view set is obtained with a 3D warping algorithm, which also performs hole-filling in the occlusion regions. The proposed MVC method, based on H.264 standard, encodes a number of reference views in a standard manner, whereas the residuals of the novel view predictions are encoded separately. The proposed MVC method is compared against simulcast coding of each view, yielding better rate-distortion performance, especially at lower bitrates.

3-D structure assisted reference view generation for H.264 based multi-view video coding

Multiple Description Coding of 3D Dynamic Meshes Based on Temporal Subsampling
Bici, M. Oguz; Akar, Gözde (2010-01-21)
In this paper, we propose a Multiple Description Coding (MDC) method for reliable transmission of compressed time consistent 3D dynamic meshes. It trades off reconstruction quality for error resilience to provide the best expected reconstruction of 3D mesh sequence at the decoder side. The method is based on partitioning the mesh frames into two sets by temporal subsampling and encoding each set independently by a 3D dynamic mesh coder. The encoded independent bitstreams or so-called descriptions are transm...
Multiple description scalar quantization based 3D mesh coding
Bici, M. Oguz; Akar, Gözde (2006-10-11)
In this paper, we address the problem of 3D Model transmission over error-prone channels using multiple description coding (MDC). The objective of MDC is to encode a source into multiple bitstreams, called descriptions, supporting multiple quality levels of decoding. Compared to layered coding techniques, each description can be decoded independently to approximate the model. In the proposed approach, the mesh geometry is compressed using multiresolution geometry compression. Then multiple descriptions are ...
HAKI: runtime verification tool for JavaScript MVC web applications
Bilge, İbrahim; Betin Can, Aysu; Department of Information Systems (2016)
In this thesis, we propose an efficient approach for locating inconsistencies in view-model bindings of JavaScript AngularJS web applications. JavaScript is one of the most common scripting languages used for developing web applications. It can be used to create flexible, efficient code thanks to its highly dynamic nature. In addition, many structural frameworks have been developed for building even more extensible and more dynamic web applications. One of the most popular of these frameworks is AngularJS w...
An antology - driven video annotation and retrieval system
Demirdizen, Goncagül; Çiçekli, Fehime Nihan; Department of Computer Engineering (2010)
In this thesis, a system, called Ontology-Driven Video Annotation and Retrieval System (OntoVARS) is developed in order to provide a video management system which is used for ontology-driven semantic content annotation and querying. The proposed system is based on MPEG-7 ontology which provides interoperability and common communication platform with other MPEG-7 ontology compatible systems. The Rhizomik MPEG-7 ontology is used as the core ontology and domain specific ontologies are integrated to the core on...
