Blind Multiple-Input Multiple-Output Image Phase Retrieval [PDF]
IEEE Transactions on Industrial Electronics, 2020 In this paper, we consider the problem of recovering the phase information of the multiple images from the multiple mixed phaseless short-time Fourier transform image measurements, which is called the blind multiple-input multiple-output image phase retrieval (BMIPR) problem. It is an inherently ill-posed problem due to the lack of the phase and mixing
