Multimedia Compression
Our current research projects include:
- 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.
- 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.
