Fig. 4 — Simulation of the proposed strategy for updating the object (top row) and the unknown incoherent OTF (bottom row). (a) The ground-truth recovery assuming the OTF is known. (b) We set the cutoff frequency of the initial OTF to be 1.5 times larger than that of the ground truth. The results with (b1-b2) and without (b3-b4) the OTF updating process. (c) We set the cutoff frequency of the initial OTF to be half of that of the ground truth. The results with (c1-c2) and w/o (c3-c4) the OTF updating process.
