| Popis: | We present a single-shot image processing method to reduce speckle noise mitigating undesired blurring effects in both amplitude and phase reconstructed images. The implementation is based on the average of multiple median filtered images with different kernel size. This approach provides final reconstructed amplitude and phase images with reduced speckle contrast and without penalizing the spatial resolution. |
