(a) Noise-free oversampled diffraction pattern of the Lena model. (b) Oversampled diffraction pattern of the Lena model with Poisson noise (Rnoise = 15%). (c) Lena model with an inset showing fine features. Final reconstructions of the Lena model obtained from the noisy diffraction pattern shown in (b) by using (d) HIO, (e) ER–HIO, (f) NR–HIO and (g) OSS. |
