Display dependent coding for 3D video on automultiscopic displays

Vikas Ramachandra, Matthias Zwicker, Truong Q. Nguyen
2008 2008 15th IEEE International Conference on Image Processing  
It is found that for the 3D scene seen on multiview displays, regions appearing at large depths are rendered blurry. The proposed method identifies such regions and uses fewer bits to code them.  ...  For compatibility with the framework of scalable multiview coding, we introduce depth scalability.  ...  These methods take advantage of the correlations between the different camera view images, and compute the disparity map.  ...

and standards for 3D quality.  ...  For the percept of depth to be convincing, consistent, and comfortable, a large number of parameters throughout the imaging and processing pipeline need to be matched correctly.  ...  For instance, in order to generate M > N views from N input views, two neighboring color images are first warped using the associated depth maps.  ...

Graph-based representation for multiview image coding [article]

Thomas Maugey, Antonio Ortega, Pascal Frossard
2013 arXiv   pre-print
We present the principles of this graph-based representation (GBR) and we build a complete prototype coding scheme for multiview images.  ...  In this paper, we propose a new representation for multiview image sets. Our approach relies on graphs to describe geometry information in a compact and controllable way.  ...  More precisely, in both GBR and LDI, the 3D points of the scene are represented once and only once, which is not the case for light field, multiview or depth-based representations.  ...

Multiview Stereo with Cascaded Epipolar RAFT [article]

Zeyu Ma, Zachary Teed, Jia Deng
2022 arXiv   pre-print
CER-MVS introduces five new changes to RAFT: epipolar cost volumes, cost volume cascading, multiview fusion of cost volumes, dynamic supervision, and multiresolution fusion of depth maps.  ...  CER-MVS is significantly different from prior work in multiview stereo. Unlike prior work, which operates by updating a 3D cost volume, CER-MVS operates by updating a disparity field.  ...  Like prior deep-learning work on multiview stereo, CER-MVS predicts individual depth maps and then fuses them, but differs significantly in how it predicts each depth map.  ...
