Multi-view Video Coding


Multiview video systems are used for capturing a scene from different viewpoints, so that 3-D information of a scene is contained in the resulting set of sequences. Such videos are emerging as a potential tool for new multimedia services, e.g., 3-D TV and free viewpoint video. Because a multiview video contains several video sequences from different cameras, widespread use of multiview video requires the design of efficient compression techniques.



A straightforward approach for multiview video encoding would be to use standard video coding techniques independently on the video sequences corresponding to each camera. To further improve coding efficiency, inter-view coding (IVC) can be applied, where block-based predictive techniques can be used that is similar to the motion compensated predictive coding techniques used in MPEG-2, H.264/AVC, etc. Please refer to [http://biron.usc.edu/~jaekim/MVC/mvcDiagram.jpg MVC diagram]

+  <li> Distributed Source Coding: Based on the distributed source coding framework, we proposed efficient scalable video coding and hyperspectral image compression systems.  Using distributed source coding tools, encoder can operate in 'open loop' leading to complexity reduction.  We also proposed efficient methods to estimate the correlation function to facilitate encoding.
-A straightforward approach for multiview video encoding would be to use standard video coding techniques independently on the video sequences corresponding to each camera. To further improve coding efficiency, inter-view coding (IVC) can be applied, where block-based predictive techniques can be used that is similar to the motion compensated predictive coding techniques used in MPEG-2, H.264/AVC, etc. Please refer to [http://biron.usc.edu/~jaekim/MVC/mvcDiagram.jpg MVC diagram]
