A unified joint reconstruction approach in structured illumination microscopy using unknown speckle patterns

The structured illumination microscopy using unknown speckle patterns has shown the capacity to surpass the Abbe's diffraction barrier, giving the possibility to design cheap and versatile SIM devices. However, the state-of-the-art joint reconstruction methods in this framework has a relatively low contrast in super-resolution part in comparison to conventional SIM and the hyper-parameter is not easy to tune. In this paper, a unified joint reconstruction approach is proposed with the hyper-parameter proportional to the noise level. Different regularization terms could be evaluated under the same model. Moreover, the degradation entailed by out-of-focus light could be solved in speckle illumination setup easily.
