“…Unfortunately, the reconstruction formulation proposed in that work is especially ill-posed due to randomness between the illumination patterns, i.e., if N img raw images are taken, there would be N img + 1 unknown variables to solve for (N img illumination patterns and 1 sample distribution). To better condition this problem, priors based on speckle statistics [46,47,49,50,52] and sample sparsity [48,51] can be introduced, pushing blind SIM to 2× resolution gain. However, to implement high-content microscopy using SIM, we desire a resolution gain of > 2×.…”
