HIONet: Deep priors based deep unfolded network for phase retrieval

WebPhase retrieval (PR) aims to recover the image of interest from the recorded phaseless measurement. Traditional PR algorithms that use hand-crafted priors suffer from low-quality reconstructions at low signal to noise ratios (SNRs). Recent efforts overcome this limitation by using deep priors, but existing algorithms ignore structural priors. WebDec 1, 2024 · In this paper, we develop an unfolded deep network based on the classic HIO method, dubbed as HIONet, to perform the reconstruction from phase-free measurements, which is benefited from the merits of both model-based and data-driven approaches.
