Figure 7. Flow chart of our reconstruction approach.

For the Richardson-Lucy deconvolutions applied in the first and final steps we use no more than 10 and 5 iterations respectively. To estimate the initial phase ϕ_j an interval Φ = [0, 2π] containing n values must be defined. The values in the interval are denoted as Φ₁, Φ₂… Φ_n. The correct reconstruction parameters and extended domains are extracted for each of the illumination pattern orientations and then used to assemble the super-resolved image I_SIM.
