Distributed Compressed Video Sensing

Abstract

This paper proposes a novel framework called Distributed Compressed Video Sensing (DISCOS) - a solution for Distributed Video Coding (DVC) based on the Compressed Sensing (CS) theory. The DISCOS framework compressively samples each video frame independently at the encoder and recovers video frames jointly at the decoder by exploiting an interframe sparsity model and by performing sparse recovery with side information. Simulation results show that DISCOS significantly outperforms the baseline CS-based scheme of intraframe-coding and intraframe-decoding. Moreover, our DISCOS framework can perform most encoding operations in the analog domain with very low-complexity. This makes DISCOS a promising candidate for real-time, practical applications where the analog to digital conversion is expensive, e.g., in Terahertz imaging.
