(a) Noise-free oversampled diffraction pattern of a biological vesicle model. (b) Oversampled diffraction pattern of the biological vesicle with Poisson noise (Rnoise = 20%). (c) The biological vesicle model and some fine features (inset). Final reconstructions of the biological vesicle obtained from the noisy diffraction pattern shown in (b) by using (d) HIO, (e) ER–HIO, (f) NR–HIO and (g) OSS. |
