Comparison of deep learning-based compressive imaging from a practitioner's viewpoint

For nearly twenty years, a multitude of Compressive Imaging (CI) techniques have been under development. Modern approaches to CI leverage the capabilities of Deep Learning (DL) tools in order to enhance both the sensing model and the reconstruction algorithm. Unfortunately, most of these DL-based CI methods have been developed by simulating the sensing process while overlooking limitations associated with the optical realization of the optimized sensing model. This article presents an outline of the foremost DL-based CI methods from a practitioner's standpoint. We conduct a comparative analysis of their performances, with a particular emphasis on practical considerations like the feasibility of the sensing matrices and resistance to noise in measurements.
