Original Image * = Compressive Sensing using Single Pixel Camera (15% measurements) Ours PSNR: 29.68 dB TVAL3 PSNR: 24.70 dB Reconstructed Image D-AMP PSNR: 26.76 dBFigure 1: We propose to use a deep generative model, RIDE [27], as an image prior for compressive signal recovery. Since RIDE models long-range dependency in images using spatial LSTM, we are able to recover the image better than other competing methods. AbstractReconstruction of signals from compressively sensed measurements is an ill-posed problem. In this paper, we leverage the recurrent generative model, RIDE, as an image prior for compressive image reconstruction. Recurrent networks can model long-range dependencies in images and hence are suitable to handle global multiplexing in reconstruction from compressive imaging. We perform MAP inference with RIDE using back-propagation to the inputs and projected gradient method. We propose an entropy thresholding based approach for preserving texture in images well. Our approach shows superior reconstructions compared to recent global reconstruction approaches like D-AMP and TVAL3 on both simulated and real data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
