A novel decoding method is proposed to improve the decoding quality of both compressed sensing (CS) frames and key frames in distributed compressive video sensing at low CS frames sampling rate. Results manifest that the decoding performance of the proposed approach at low sampling rate outperforms the state-of-the-art block-based compressed sensing-based codecs.
