Abstract

The distributed compressive video sensing (DCVS) system greatly reduces the pressure on the encoder by transferring the computational complexity to the decoder, which is suitable for the limited-resource video sensing and transmission environment, in the meantime, get the better performance from key (K) frames and non-key (CS) frames. In this paper, we use the approximate message passing (AMP) algorithm reconstruct the K-frames. In order to improve the quality of the reconstructed K-frames, we add the block-matching 3D filtering (BM3D) denoising strategy based on the AMP algorithm. For the CS-frames, we improve the reconstructed CS-frames by improving the accuracy of side information (SI) frames by proposing a new high efficiency video coding (HEVC) motion estimation (ME) algorithm with motion vector (MV) prediction method. After we obtain the SI frames and combine the compressed value of the CS-frames with the side information (SI) fusion algorithm based on the difference compensation algorithm, the high accuracy SI frame is integrated into the reconstruction algorithm of the CS-frames. The experimental results demonstrate that our algorithms achieve higher subjective visual quality and peak signal-to-noise ratio than the traditional methods.
