Our current research projects include:<br />
</p><br />
<ul><br />
<li> Multimedia Communication: We proposed a new coding scheme, Multiple Description Layered Coding (MDLC), which combines the advantages of layered coding (LC) and multiple description coding (MDC) to provide reliable video communication over a wider range of network scenarios and application requirements. A runtime scheduling algorithm is also developed for the MDLC system, to reduce its redundancy to match the channel behavior. The MDLC system is implemented by adding enhancement to the original MPEG-4 FGS.<br />
<br />
<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.<br />

</p><br />
<ul><br />
<li> Multimedia Communication: We proposed a new coding scheme, Multiple Description Layered Coding (MDLC), which combines the advantages of layered coding (LC) and multiple description coding (MDC) to provide reliable video communication over a wider range of network scenarios and application requirements. A runtime scheduling algorithm is also developed for the MDLC system, to reduce its redundancy to match the channel behavior. The MDLC system is implemented by adding enhancement to the original MPEG-4 FGS.<br />
<br />
<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.<br />

<div><P><B>Multi-view Video Coding</B></P><br />
<br />
<p><br />
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.<br />
</p><br />
<br />
<p><br />
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]<br />
