Simulation results for (A–H) limited phase wrap and (I–P) extensive phase wrap case. For each case, enhanced phase images were generated using 8 different methods: (A and I) Homodyne-rectangular filtering, (B and J) Homodyne-Gaussian filtering, (C and K) Homodyne-Hanning filtering, (D and L) Homodyne-Hamming filter, (E and M) phase unwrapping-smoothing, (F and N) phase unwrapping-Gaussian filtering, (G and O) phase unwrapping-Hanning filtering, (H and P) phase unwrapping-Hamming filtering. All filtering methods used a filter size of 32 pixels. Smoothing factors was 21 pixels.
