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 recently emerging Compressed Sensing theory. The DISCOS framework compressively samples each video frame independently at the encoder. However, it recovers video frames jointly at the decoder by exploiting an interframe sparsity model and by performing sparse recovery with side information. In particular, along with global frame-based measurements, the DISCOS en… Show more

“…The GPSR algorithm [12] and the smoothed projected Landweber (SPL) algorithm [13] are utilized for the CS reconstruction of the key frames and the NK frames, respectively. We compare our DCVS codec with four representative DCVS codecs in the literature: DISCOS [1], DISACOS [2], RDO-DCVS [3], and PA-DCVS [4]. For fair comparison, all the DCVS codecs use the same configuration to sample and reconstruct the key frames.…”

“…Most current efforts in DCVS have been focused on enhancing the objective coding performance [1]- [3]. Since the human visual system (HVS) is the ultimate receiver of visual signals, it is worth investigating the perception-based DCVS codec.…”

“…wavelet, DCT), each CS block is represented using a matrix composed of a dictionary of temporal neighboring blocks. While this is shown in [62] to far outperform other methods, it does require a "motion-vector-like" operation at the source node. Because of the high complexity of motion vector calculations, they cannot be implemented on a simple low-complexity and energy constrained sensor node, and are therefore not appropriate for WMSNs.…”
