Compressed Sensing Image Reconstruction Based on Convolutional Neural Network

Abstract: Compressed sensing theory is widely used in image and video signal processing because of its low coding complexity, resource saving, and strong anti-interference ability. Although the compression sensing theory solves the problems brought by the traditional signal processing methods to a certain extent, it also encounters some new problems: the reconstruction time is long and the algorithm complexity is high. In order to solve these problems and further improve the quality of image processing, a new convolutio… Show more

“…The quantitative results (Fig. 5) show that the PSNR of CGI with CS-CNN is average 7% higher than that of CGI with DL under the same reconstructed frame number, SSIM increased by 12% on average [26]. Consequently, under the condition of producing the same image quality, CS-CNN has the faster imaging speed.…”

“…Thus, as the signal size grows, so does the network, imposing a large computational complexity on the training algorithm and risking potential overfitting. The solution proposed in [104] and adopted by similar approaches [69,81] is to divide the signal into smaller blocks and then sense/reconstruct each block separately. From the reconstruction time point of view, the simulation results show that this approach beats the other methods, whereas the of quality of the reconstruction does not necessarily overshadow that of other state-of-the-art recovery algorithms.…”

“…One of its drawbacks is the fact that this approach uses a blocky measurement matrix, to reduce the network complexity and hence, the training time, and therefore, ReconNet does not exploit potentially strong dependencies that may exist between the reconstructions of different blocks. CombNet provides improved quality of reconstruction by using a deeper network structure and a smaller convolution core [81].…”
