Abstract
In the last few years new research has demonstrated that distributed source
coding (DSC) techniques can be applied to multiple media compression scenarios
and have demonstrated that these techniques have potential benefits in terms of
encoding complexity and error resilience. DSC originates in the information
theoretical work of Slepian, Wolf, Wyner and Ziv in the 1970s. In this talk we
first provide a short introduction to the key intuitions behind DSC. We then
discuss several applications of these techniques: video compression with
flexible playback, scalable video coding and compression of hyperspectral
imagery. These applications help us illustrate the potential of these techniques
as well as the
very significant remaining research challenges they pose.
We will also provide a brief overview of other current research activities in
the compresssion research group at USC, including information representation and
coding in sensor networks, multiview video coding, video compression with
computation error tolerance and analysis of DNA data.
