Low complexity side information for distributed compressed video coding

Distributed Video coding based on compressed sensing is considered in this paper. Side information plays an important role in the quality of decoded non-key video frames. Existing systems generate side information based on the decoded key frames and the processes are quite complicated, increasing the computation burden at the decoder. We propose a side information generation method that is founded on the high statistical correlation between compressed sensing measurements of key frames and non-key frames. The proposed technique is simple and simulation results show that better rate distortion performance can be obtained in comparison with motion compensated interpolation.
